NexTek is proud to announce the availability of a new ultra-wideband surge protection device for Radio and RF communication systems. With a compact design, an extremely wide pass band, and the ability to pass DC power in addition to RF energy this unit is well-suited for a multitude of bands, applications, and systems that require high-performance lightning protection in a compact package.
Wideband – DC to 12.5GHz
Compact – Ultra-Small Footprint
Robust – High Performance Gas Discharge Tube
Weatherproof – IP68 Dust and Waterproof
Value – Perfect for a wide array of uses, at a good value
The PTCONMONF20G [male-female] and PTCONFONF20G [female-female] units provide a single device that can be used to protect most RF Applications with a single solution. This should allow users with a wideband or multi-band system, or users who have a wide variety of pass bands available across their products or systems, to use a single arrestor and reduce P/Ns, stocking costs, etc.
This unit is also perfect for users who need Type N protection but have no room to add a bulky arrestor. In this case, simply replace a normal un-protected feedthrough connector with this protected version…and you’ll have integrated high-performance lightning and surge protection with virtually no space or weight penalty!

Although this new Technical Note covering how to test/screen an arrestor to ensure that it is working and operating properly was specifically created in reference to our FPL series of units designed to protect GPS and other Global Navigation equipment…the input here also applies to the majority of the NexTek FPL and FPN series units. Most of the FPL and FPN series, including the FPL GPS arrestors, use multiple stages of protection circuitry inside.
This relative complexity makes the FPL and FPN series Fine Protectors a bit more complex to test properly, when compared to other common types such as Gas Discharge Tube or Quarter Wavelength Shorted Stub arrestors.
Operational/Protection Voltage Testing
- Without an actual lightning tester (such as the common 1.2×50µs / 8×20µs Induced Lightning waveform testers,) it is difficult to completely verify Transient Response and Performance.
- The lowest-voltage component is usually the only one that can be tested using a Diode Tester or Slow Rising DC Power Supply & Multimeter combination. For NexTek FPL and FPN series devices, this usually means a fast-acting semiconductor Protection Diode that is responsible for final energy cleanup. However, this component is usually the least robust in terms of Transient Current Handling so if it remains intact and operating within specs…the entire unit should be working OK.
Test Voltage Levels – Units may have +1V, +3.3V, +5V, +12V, +24, or other common Protection Voltage ratings
Continuity and Insulation Testing
- Any FPL or FPN series units that are rated to pass DC Power through the unit will test positive for continuity between center pins, when using a Multimeter tool.
RF Thru-Performance / Proper Radio Operation
- One of the simplest ways to test the basic functionality of any arrestor, not just the FPL and FPN series units, is to test the unit in a radio installation and verify proper system operation. This alone is a positive indicator that the unit is operating properly and is probably not damaged.

The Neverending Quest For Size Reduction
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

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;
