New: Rugged, Ultra Low Loss, Coax Cables

The Gamma Electronics team is happy to announce a new addition to our cable line of products: Rugged, Ultra Low Loss, RF Coaxial Cables. 

Below we provide answers to, (what we assume will be), common questions and we provide some test data as well.

Reduce RF Interference with the Gamma Suppressor Boot

What does “Ultra Low Loss” Mean?

These new cables are an upgrade over braided shield cables, (i.e. LMR 195 & 400), which are often referred to as low loss cables.  While it’s true that braided shield cables tend to produce good low loss results, our new Ultra Low Loss cables significantly improve both the VSWR and insertion loss results over low loss cables, hence the name, “Ultra Low Loss.”

The Test Results

We’ve compared our cables against LMR 195 & 400 cables to find improved VSWR results, as well as up to a 25% improvement on insertion loss results.  Our Rugged, Ultra Low Loss Cables will make it so that more of your signal gets to the desired destination.  You can see the test results in the chart below, where we compared these new cables, (labeled as S-FLEX 1/4″), against both LMR 400 and LMR 195.

Ultra Low Loss Coax Cables Test Results

It’s important to note that a drop of 1 dB amounts to about a 26% improvement.  For those who might not be familiar, measurements like dB are not done on a linear scale but instead utilize a logarithmic scale.  Logarithmic scales are intentionally used to make numbers that would be spaced apart from one another on an exponential level, easier to read on a single chart.   So, for example, in the Insertion Loss test results above, a 1 dB improvement may seem like “only 1 dB,” but it is actually around a 25% improvement.

What Makes these Cables Different?

The single biggest difference between our Rugged, Ultra Low Loss Cables, compared to cables like LMR 195 & 400, is the cable’s outer shield.  The outer shield, (sometimes also referred to as the outer conductor), is the part of the cable that sits just inside the cable jacket.  It’s called a shield as it rejects outside interference, but it also acts as a conductor that helps propogate the signal through the cable.

Low Loss cables use a braided shield, which are made up of many small, woven, metallic fibers.  Those fibers create a shield to help block external, electromagnetic interference.  Low Loss cables also require a foil conductor, that sits just inside the braided shield, to act as a conductor, which helps conduct and propogate signal through the cable.  Low Loss cables need this two piece solution that produces good, but not great results. 

Our Ultra Low Loss cables on the other hand, utilize a spiraled, corrugated copper design, which accomplishes both the rejection of outside interference as well as conducting signal within the cable, with great results.

Braided Shield Cable Interior

A braided shield is, simply put, an inferior outer shield/conductor compared to the spiraled, corrugated copper used on the Ultra Low Loss coaxial cables.  A simple bend or twist in the cable could easily introduce a gap in the braided shield, which is not going to happen on a corrugated copper cable, unless there is a noticeable break in the cable, (also unlikely to happen).  Additionally, the braided shield is not as durable, which we’ll go into more below.

What Makes these Cables Rugged?

Ultra Low Loss cables are far better suited to withstand the wear and tear that comes with being deployed on cell phone, WISP, or fixed wireless applications.  Braided shield cables, as a comparison, can be easily knicked or cut, resulting in a gap in the outer shield/conductor, that leaks signal while also allowing for outside interference to work its way into the cable.  In addition, that knick/cut in the cable has introduced an entry point for moisture into the cable.

Ultra Low Loss cables, on the other hand, have that superior outer shield that will better withstand knicks and cuts.  It’s a single piece of copper as compared to a bunch of braided metal fibers, making it tougher and more durable.  Even if the cable jacket were to be knicked or cut it’s unlikely the cable’s outer shield would be cut as well.

Lastly, the Ultra Low Loss cables are soldered instead of being crimped.  Not only does this give better test results, but in simple pull tests we found that braided shield cables needed far less pull to come apart than the Rugged, Ultra Low Loss Cables.  A strong enough tug and the connector on braided shield cables would pop off, but not so with the Ultra Low Loss cables.  The Rugged, Ultra Low Loss coaxial cables required one side to be held in place and far more pounds of pressure to be applied in order to come apart.

Are the Rugged, Ultra Low Loss Cables Flexible?

Yes, very.  The Rugged, Ultra Low Loss cables are actually Superflex, quarter inch cables.  These cables do have more rigidity to them than you will find with LMR cables, but they are far more flexible than something like a 1/2″ annular and/or standard coaxial cable.  These cables are able to be flexible because, (unlike annular or standard cables), their outer shield is spiraled.

What Connectors Can I Get on the Rugged, Ultra Low Loss, Coaxial Cable?

We currently offer this cable in three connector varations: RPSMA to RPSMA, RPSMA to Type N, and Type N to Type N.

We also offer different length cables in these different connector variations, so make sure to check out their individual pages for more details.

Do You Offer the Rugged, Ultra Low Loss Cable with Weatherproofing?

Absolutely.  We offer all variations of the Rugged, Ultra Low Loss cable with our industry leading, silicone cold shrink tubing.  We have cold shrink tubing designed to perfectly match RPSMA connections, (SDL-SMA-60) and Type N connections, (SDL-TNS-65), all while creating a watertight seal on a 1/4″ superflex cable.  Our cold shrink tubing provides an IP68 rated, watertight seal that simply cannot be matched.

Conclusion

Our new, Rugged, Ultra Low Loss Coaxial Cables are a solution we chose to bring to the market as we saw an increasing demand, (specifically from the WISP industry), for cables that outperformed braided shield/low loss cables, while not having to be quite as high-end as Low PIM cables.  We were able to utilize some of the technology from our Low PIM cables in this new offering, while providing a better price point for our customers.

Assuming you don’t need low PIM cables, the Rugged, Ultra Low Loss coaxial cable is the “best value for your money” cable on the market, especially when you consider the perfectly matched cold shrink tubing included with the cable.

Reduce RF Interference with the Gamma Suppressor Boot

Reduce RF Interference with the Gamma Suppressor Boot

“What if we made a boot that could reduce RF interference?”  That was the question our engineering team set out to answer.  We’ve been making boots that provide IP68 level weather protection for coaxial cable connections for years, but what if we took it a step further?  What if we made a boot that provides weather protection and reduces RF (Radio Frequency) interference?
Reduce RF Interference with the Gamma Suppressor Boot

Proof-of-Concept

Immediately the ideas began to flow on how we might accomplish this.  The overall boot design was already in place as our engineering team has created boots for coaxial connectors ranging from NEX10 to 7/16 DIN.  The more pressing question became “what would the boot be made from?”  All our weatherproof boots up to this point have been designed from silicone because of silicone’s incredible weather protection properties and resistance to environmental exposure.  Pure silicone rubber does not however block RF signal that could easily find it’s way into nearby antennas from loose leaking connectors.

So the next question became, what material would block or reduce outside RF interference, and could a rubber style boot be manufactured from such a material?  Those were the two key criteria that would have to be met for this to work and, needless to say, this brought about quite a bit of testing. Our team started by testing samples of different silicone rubber composite materials to see which ones would effectively attenuate, (or reduce), undesired RF egress, while still providing the level of weather protection our customers have come to expect from our boots.

To find the right material we had to put it through rigorous testing, which, (to vastly oversimplify the process), can be stated in a few steps.  First, we would transmit an RF signal.  Next, we would receive and measure the intensity of that RF signal. Lastly, we would place different materials in between where the signal was generated and where it was measured to see if the material made any noticeable difference to the RF signal, (i.e., block and/or reduce signal levels).  The basic premise of this test is illustrated below.

This process sounds basic but there are so many different ways to do it that we had to be sure we were using methods that would produce trustworthy test results.  One way we found success in testing material was by generating the RF signals with a PIM tester which sent two RF signals (via cable) to a small antenna unit.  The antenna unit would transmit the RF signals to be picked up by a field probe (receiver), with the results being shown on a spectrum analyzer, (illustrated below).

Below you can see some of the real-world equipment we utilized during the material testing phase of this process.

PIM Testing Equipment

Small Antenna Unit (Transmitter)

Magnetic Near-Field Probe (Receiver)

Spectrum Analyzer

We tested a number of different materials with this type of testing with some variations.  As can be seen in the spectrum analyzer below we were able to pick up the two test frequencies, (1805 and 1880 MHz), quite clearly with this testing method.

Spectrum analyzer read out of RF signal with no boot material

The next step was to test out different materials and see if those materials would impact the strength of those transmitted frequencies.  Typically, we would take the material and place it over the antenna unit and check the spectrum analyzer for a difference in the strength of the signal.

Antenna covered with material

We tested several materials, some of which had zero impact on the strength of the RF signal with others having negligible results.  However, after going through several different iterations of materials we found a silicone rubber composite material that significantly attenuated the RF signals, as can be seen in the image below.

Spectrum Analyzer Read-Out of RF Signal with Boot Material in use

When compared to the earlier photo you can see that this composite material resulted in a reduction (or attenuation) of about 15-20 dB, a massive reduction.  This led us to believe we had found the composite material that could be molded into a boot and realistically reduce RF interference.  Here are the before and after results side by side.

We should note that these are proof-of-concept results and that a drop this significant, while fantastic, is not what would be expected in real-world results.  In these tests we were looking for an effective material, but there is almost no real-world scenario where we would take that material and wrap it around the front of an antenna,  (as we did in these early tests).  Once we found a material that worked, wrapping it around the front of the antenna unit should have drastic results, but not the same results as would be produced by a boot made of the same material over a connector.

Truth be told, what is shown above is only a fraction of the amount of testing that took place to choose the right material.  Furthermore, the more testing we did the more refined our testing process became, (which can be seen in the actual boot testing below).  These proof-of-concept tests were simply to make it easy for us to identify the right material that we would attempt to make a boot out of and, (of course), to see if our concept could work.

From Theory to Practice

It was time to take the material and put it into boot form. Luckily, we are well versed on manufacturing weatherproof boots and we were able to produce them with ease.  We were very pleased that the boots did in fact have the elasticty we were looking for, and that the install/uninstall experience is essentially identical to our normal weatherproofing boots.  In fact, if you were going by the feel of the boot alone you might find it difficult to tell the difference between our normal weatherproof boots compared to the Suppressor Boot.  So we had now met one of the 2 needed criteria.

Gamma 7/16 DIN Suppressor Boot

Gamma Suppressor Boot

Antenna Unit

Once the boots were made, we knew we had to test them again and that the testing process would look a bit different.  We improved upon the testing process for the actual boot while utilizing the basic idea used in the proof of concept tests.

First, like the proof-of-concept test, we generated RF signal from our PIM tester and sent the signals, (via cable), to the antenna unit.  This time we took all the testing outdoors to help eliminate any wall reflections.

Next, we aimed the antenna at a horn antenna designed to receive the RF frequencies being transmitted much like water going into a funnel.

RF Signal Radiated by a Waveguide Antenna and Collected by a Horn Antenna

Inside the horn antenna cavity is a dipole feed element measuring the intensity of the RF frequencies being transmitted to it.  The signal intensities are then measured by our trusty spectrum analyzer.

Feed inside of Horn Antenna Cavity

PIM Testing Equipment next to Spectrum Analyzer

Like before, the spectrum analyzer would tell us how much of the transmited signals  were being picked up and how much was attenuated by the suppressor boot.  Note, in the photo above that we covered the spectrum in two different boxes, one of which is covered in foil, to shield it from any outside interference. We did this despite the fact that it should only being showing frequencies coming via the cable from the horn antenna, but we wanted to make sure we were eliminating any potential interference.

Testing the Boot

In order to know how much RF signal was or was not being affected by the boot we first had to measure how much the transmitted frequencies were being picked up by this testing setup.  The first image below shows the results with no boot over the feed (unattenuated).

Like the proof-of-concept testing we can clearly see two frequencies being transmitted: 1805 and 1880 MHz.

Next, we placed the Suppressor Boot over the feed inside the horn antenna, (click photo to enlarge).  As soon as we placed the boot over the feed there was an immediate signal drop shown on the spectrum analyzer.  You can see the before & after photos below.

With the suppressor boot over the feed we saw an immediate drop of at least 10 dB.  Don’t let the spectrum analyzer fool you, a 10 dB drop is huge.  Decibels (dB) are not charted on a linear scale, instead the spectrum analyzer is giving us a logarithmic reading.  In other words, a drop of 10 dB is not simply a loss of 10 units but amounts to a 90% reduction in signal intensity.

If the Suppressor Boot were to reduce the signal by 3 dB that would mean it effectively reduced the original signal’s power by half.  A 10 dB reduction means the Suppressor Boot has effectively reduced the RF signal to 1/10 of the original signal.  It doesn’t quite look that way in the test result but that’s the nature of a logarithmic scale: the logarithmic scale is designed to make numbers that are greatly spaced apart easier to read on a graph.

Testing for Real-World Scenarios

Next, we performed a test that was more like a real-world scenario.  Instead of using a waveguide antenna to transmit the frequencies we instead created a “leaky connector” scenario by sending the signal from the PIM tester to a 50 Ohm dummy load, (commonly used when testing RF cables).  We used a Type N connector and only hand tightened the connector to the load.  We then placed this leaky connection in front of the horn antenna.

In essence, the leaky connection is replacing the antenna as the transmitter in this test.  As can be seen in the photo below the cable did have the Suppressor Boot on it, (in preparation for the next step in the test), but the boot was not covering the connection.

For this test, the RF power of each frequency from the PIM generator was 43 dBm versus 33 dBm, (which is what we used in the previous test with the waveguide antenna). This increase in power was to compensate for the reduced radiating efficiency of the leaking connector compared to that of the waveguide antenna.  In other words, the leaky connector doesn’t radiate signal the way the waveguide antenna does and we wanted to make the signal clearly visible when seen on the spectrum analyzer.  If you compare the photo to below to earlier tests above you can see the change in power on the spectrum analyzer.  Each horizontal line on the spectrum analyzer represents a division of 10 dB, and the results in the leaky connector test do show up as 10 dB higher than previous tests due to this power change.

The reduced radiating efficiency also resulted in a larger signal-to-noise ratio. As opposed to previous tests with the waveguide antenna where we really only saw the 1805 and 1880 MHz frequencies, we are now seeing more noise showing up alongside the signal on the spectrum analyzer.  Again, the results from a leaky connector were not going to be as clean and clear as results from the waveguide antenna.  As a result of this larger signal-to-noise ratio, the spectrum analyzer was operated with a much larger gain setting to help separate the signal from the noise.  The noise at zero-frequency and frequencies greater than 1880 MHz is comparable to the signal itself as seen in the pictures below. However, in each test, the gain was set to a fixed value before the Suppressor Boot was applied so the before-and-after signals are apples-to-apples comparisons.

Long story short, we made some adjustments to make the results more clearly visible but those adjustments had no bearing in determining how effectively the boot would work.

The only thing left to do now was to cover the leaky connection with the Suppressor Boot and see if there was a drop in intensity of any significance on the spectrum analyzer.

It was the moment of truth.  Months of work came down to this test.

Just as we saw in the previous test, there is at least 10 dB in attenuation/reduction.  A massive reduction.  Again the 10 dB reduction indicates that the frequency intensity has been reduced to 1/10 of its original intensity.  Here’s the results without and with the boot side by side.

We’ve tested the Suppressor Boot time and time again and each time it produces the same results: at least 10 dB attenuation.  We had achieved what we set out to do.  We had successfully found the right material and manufactured it into a great RF interference attenuation/reduction solution.

What It All Means

A reduction of about 10 dB is impressive, but what does it really mean?

Anyone with familiarity of cell phone towers or fixed wireless in general is aware of the often dozens of cables being utilized at a single site, all of them carrying RF signal.  With that much electromagnetic signal flowing any type of egress or leakage can quickly become a major problem as those signals can interfere with one another, resulting in poor service and/or cross talk.  In some cases, interfering with the wrong frequencies can even result in being fined.

Over the past ten years, the problem of CATV, 4G LTE and now 5G signal interfering with each other is compounding. RF interference is a huge problem for Cable TV providers as they are strictly regulated by the FCC and run the risk of getting fined if their RF networks are leaking. In fact, it is well known that when they leak RF signal into the air AT&T, Verizon or T-mobile will come knocking on their door letting them know that they their CATV network is interfering in their network. If the cable TV provider is unresponsive, it can lead to significant fines. It all has to do with a hierarchy and who has the rights to the frequencies transmitted. The shared frequencies of 600 MHZ and 700 to 800 MHZ is especially problematic.  The Gamma Suppressor Boot was designed largely with these problems in mind.

 
The testing above shows that if a single connection were to be leaking signal that the Gamma Suppressor Boot would greatly help contain that RF leakage.  The boot is designed to simply reduce and/or block RF frequency from getting through and possibly finding its way into an antenna, which would introduce Passive Intermodulation, (PIM), to the system.  Add to this that the Gamma Suppressor Boot also provides IP68 rated weather protection and the incredibly fast install/uninstall process, and you have an easy-to-use solution providing multiple layers of protection.

New Custom RF Coaxial Cable Variations

In our efforts to meet the demands of the telecommunications and fixed wireless industries we have added 3 new variations that are now available to our customers in need of customized RF coaxial cables.  We are now able to offer quarter inch (1/4″) superflex cable, NEX10 connectors, as well as a new and improved Type N connector.

You can learn more about each below.

New Weatherproofing Product Variations from Gamma Electronics

Quarter Inch (1/4″) Superflex Coaxial Cable

Gamma Electronics Standard and Superflex RF Cables

One of the first key additions now available as a custom RF cable option is our quarter inch (1/4) superflex cable.  With the growth of 5G we’ve seen greater demand for smaller cables, specifically cables that can pair easily with NEX10 connectors.  While we’ve been offering the 1/4 inch superflex cable on our NEX10 to 4.3-10 cables for more than a year we are excited to now offer it as a custom RF cable option.

The 1/4 inch Superflex adds to our half inch Superflex and half inch Standard (or annular) options that we have been offering for years.

Gamma Low PIM, RF Coaxial Cable options

Alongside the 1/4 inch superflex cable we have also been adding more and more RF weatherproofing options to go with these cables, which you can find by clicking here.

NEX10® Connector

With the growth of 5G we’ve seen increased demands not only for quarter inch superflex cable but for NEX10 connectors as well.  These connectors perform incredibly well in low PIM applications and help conserve space on what are often tightly packed antennas and radios.

In addition to offering the NEX10 connector as a custom RF cable option we also lead the telecom industry in terms of offering weatherproofing for the NEX10 connector.  We have one of the few NEX10 weatherproof boots available on the market as well as some of the only cold shrink tubing capable of shrinking down small and tight enough to create a watertight seal on NEX10 connections.

Updated Type N Connector

Gamma Electronics Standard and Superflex RF Cables

In addition to the new variations above we are also pleased to announce an update to our Type N Connectors, which has been one of our most popular custom cable options that we’ve provided to customers over the years.  While we’ve had great success with our N type connections over the years we’re still always looking for ways to improve our products.

Our updated Type N connector is a bit longer than what we’ve offered previously, making it a more robust connector that will better withstand the wear and tear of outdoor use.  Like our Type N connector of the past it is made of tri-metal albaloy and provides all the same benefits that come with that, (learn more about the benefits of tri-metal albaloy connectors here).  The new Type N connector has also improved and helped to streamline our cable assembly process when using these types of connectors, while still providing the excellent low PIM results that we guarantee with each of our low PIM cables.

2 New Weatherproofing Product Variations

Gamma Electronics Blog

2 New Weatherproofing Product Variations

The Gamma Electronics team is excited to share the addition of 2 new product variations to our RF weatherproofing line of products: Clear Cold Shrink tubing and 2.2-5 Weatherproof Boots.

With the addition of these products we continue to add to and lead the fixed wireless industry in terms of RF weatherproofing options and solutions.

New Weatherproofing Product Variations from Gamma Electronics
Gamma Clear Cold Shrink Tubing

In recent months we’ve received numerous requests for cold shrink tubing that would allow installers to see cables and connections after the cold shrink had been installed.  Our new, clear cold shrink tubing has been designed to do just that and has been specifically designed for wires 2-10 AWG sized wires often in use for power on radios.  Finally it’s easier to give those power connections an IP68 rated seal while still being able to see the connection beneath it.

We have 2 variations of the clear silicone cold shrink.  The SDL-134-50-CLR, which is 50mm (1.96 inches) in length, shrinks down to 4mm, and is designed specifically for 8-10 AWG wires.  The SDL-245-65-CLR is 65 mm in length (2.56 inches), shrinks down to 5mm, and is designed for 2-6 AWG wires.

Gamma 2.2-5 Weatherproof Boot
Gamma 2.2-5 Weatherproof Boot

Another request we’ve received in recent months has been for a weatherproof boot specific to 2.2-5 connectors.  The BT-225-COAX25 is made of silicone and provides IP68 rated protection for 2.2-5 connections that are installed on quarter inch sized cables.  This boot marks the first time Gamma Electronics has made a boot designed for 2.2-5 connections, or any type of RF weatherproofing designed specifically with 2.2-5 connections in mind.

Gamma Electronics’ new Clear Cold Shrink Tubing as well as the 2.2-5 Weatherproof Boot are already available to purchase.
