Product Launch
NexTek Announces New Product – Type N Sampler Port
Westford, MA – – NexTek, LLC. has been a World -Class leading designer, developer, and manufacturer of standard and custom coaxial surge protectors and high current AC/DC EMI filters for Commercial, Medical, Avionics, SATCOM, Power Supply, Military and Government markets for over 30 years, and proudly announces a new product series for immediate release.
The “RF Sampler” is a valuable device for monitoring RF Signals, carrier RF imbalances and power outs, noise, and interference. Ideally, the device should be integrated permanently into the cable run, so that it can quickly assist with troubleshooting should the need arise. This unit can also be utilized while passing DC on the center pin. Because the monitoring device is permanently mounted, it allows a technician to easily diagnose many cell-site issues without interrupting service.

NEW RELEASE: Wideband Lightning Protection – DC to 12.5GHz with Type N Connectors
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.
Features
-
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!

Product Bulletin – Integrate RF Surge and Lightning Protection Without Paying a Size or Weight Penalty!
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
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!
Threat Types – Lightning, Static (ESD), and EMP

Compact DC Block Arrestors For Radio Protection – Featured Product
We have added NexTek’s new coaxial arrestor product to the website and product selection tool, and you can now find information about all four variations!
The PTI series provides effective protection in an extremely compact form factor, and includes a series capacitor to block DC energy and further reduce the amount of energy that gets past and flows into the radio being protected. This series capacitor guarantees effective protection from the Gas Discharge Tube front-end by eliminating the need to rely on or coordinate with the output-side capacitor of your radio.
Available with a TNC (f) bulkhead and SMA (f) connectors, in a range of RF pass band and RF Power ratings. See below and explore the datasheets to learn additional details!
Features:
- Excellent Response and Residual Energy Reduction
- Compact TNC to SMA Bulkhead Protector
- Low VSWR and Insertion Loss
