Although probably our best-known type of solution, we wanted to take the opportunity to start off 2017 by highlighting Lightning Protection for coaxial RF applications. Fundamentally, the purpose of these devices is to provide high-performance Lightning & Surge Protection for Radio and Electronic Systems and their Users. This can be as simple as protecting a radio itself, or as complex as providing protection to the entire platform or system the protection is being installed upon.
You can see the common areas where protection is installed called out as A, B, and C in the diagram above. This is an over-simplification and does not exactly represent most actual installations, but it does a good job representing the various ways and reasons that a coaxial cable can be installed outside and therefore represent a potential ingress path for Transient Lightning Energy.
Lightning damage is a leading cause of radio damage in many locations and systems around the world. Anywhere a coaxial cable or radio antenna is run outside in an exposed location, there is a potential need for an arrestor/protector on the line as well.
While we do specialize in coaxial connectorized solutions where RF Energy must be passed during normal usage, we also do have many years of experience in designing and consulting on all sorts of Surge Protection devices… From Lightning Arrestors for AC, DC, or Serial/Comms lines, to providing multi-faceted protection that is as effective against Static/ESD and HEMP/NEMP energy as it is against standard Lightning transients.
As with most technologies, RF and Wireless system design is an ever-changing and shifting world. As certain technologies or RF bands become popular, others fade away.
However, the one ever-present force on the industry is the steady, but relentless, push towards smaller size and better integration over time.
Lightning/Surge Protection at the PCB Level?
Here at NexTek we understand the desire to bring things into the box, or even all the way onto the Radio PCB… However, we also know that Lightning Transients contain too much energy to deal with safely at the PCB Level… Trace widths, ground place areas, and the components themselves all become limiting factors that will prevent complete and effective protection.
Given this reality, the last place where it is reasonable and safe to protect against Lightning or other Surge events is at the radio’s box or chassis level. By replacing the normal I/O connector with a protected version, designer can ensure that they have high-performance protection without paying any significant size or weight penalty. As long as the radio’s chassis is grounded well, the bulk of the Transient Energy will be drained safely to ground before entering the box and/or the PCB itself.
It may still be advisable to install some simple protection on the PCB, but only for final clean-up…Something like a small Protection Diode coupled with a DC Blocking Capacitor (if possible for your application) would provide plenty of protection against any residual energy that gets past the Protected I/O Connector.
Maximum Protection in the Minimum Amount of Space
Below, you can see an array of our Ultra-Compact protection options… They all include high-performance lightning protection, and are available in a wide variety of connector configurations on both the Input and Output side.
Outside Connector Options – Type N, TNC, SMA
Inside Connector Options – SMA, MMCX, RG188, RG316, and more!
We are happy to announce the recent release of a brand-new two-page bulletin and brochure, featuring our range of compact high-performance arrestors. Whether you are working on a new design, or trying to retrofit something onto an existing one…these ultra-small options are ideal for any application where size is a critical design factor.
Instead of trying to add some (likely inadequate) transient protection on-board, or having to go all the way to a traditional external arrestor mounted somewhere on the cable run…It is now possible to integrate world-class protection against Lightning, Static (ESD) or High-Speed EMP into a bulkhead connector that will easily replace most existing I/O feedthrus!
With the wide array of connector options and frequency ranges available, you should be able to find a solution for any application. Learn more and download the new Product Bulletin by following the jump below;

Special Announcement – PTC-F02 Design Revision and Updated Datasheet
For those customers who are currently using or considering the use of our 75Ohm F Type Arrestor [P/N PTC-F02], we have an updated datasheet and drawings to share with you!
Up until recently, the PTC-F02 has been one of our oldest designs. Developed in partnership with a large Internet Service Provider in the 1990s, this unit provided cutting-edge performance for the time and remains the highest performing F-Type lightning arrestor available. However, we wanted to incorporate some of the modern design and manufacturing techniques that we have developed since this unit was first made, and as a result we have given it a complete revision and update.
All outer dimensions are generally the same, and all of the specific thread sizes and diameters remain identical to the original. In other words… you will not notice a difference, and instead you will continue to experience class-leading protection and performance for 75Ohm TV/Cable/Satellite or Intermediate Frequency (IF) line applications.
Available with SMA and TNC connectors, our G-Class arrestors (The PTCSAFSAF20G and the PTCTNFSAF20G, for example) cover a wider RF Band than any other coaxial protection design in the world. Because of the exceptional wideband performance from DC all the way up to 11 or 12.5GHz, there is no arrestor available today that will cover the same number of potential applications. When the wideband ratings are combined with the extremely small form factor of these units, there is truly no other arrestor out there which can come close.
These units are perfect for retrofit or other installations where space is at a premium, or those who simply want a high quality protector that takes up minimal space! In fact, these fully featured lightning arrestors barely take up any more space than a typical connector feedthru that contains no protection at all!
Also, keep in mind that like all NexTek solutions….
All G-Class arrestors are Designed, Engineered, Assembled, and Tested here in the United States!
This design incorporates 30 Years of Experience and Expertise into every feature and detail.
They are truly High Quality Advanced Designs, ready for the most demanding applications.

This week’s featured article is a Technical Article previously published in Interference Technology magazine. This in-depth article contains details and information about providing Lightning and Surge protection for coaxial and RF applications operating in the 4 to 6GHz range.
The widely used Public Safety (4.9GHz),UNII (5.6GHz), and ISM (5.8GHz) band applications all operate within this frequency window, so there are a multitude of applications and users around the world.
High-Frequency applications within this range can be treated different in terms of the Protection Design and Technology used on this type of system. For example, the relatively high frequency range means that Quarter Wavelength Stub arrestors are ideal protectors for any application where DC Pass is not required!
