Featured Threat Type – Lightning Protection for Radio and Communication Lines

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.


Simplified Diagram Showing Typical Wireless Communications Installation – Potential Arrestor Placement Areas are A, B, and C.

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.

Compact Surge Protection – New Product Bulletin Available!


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;

Extremely Compact Lightning Arrestor Ideal for Mounting Inside Radio Chassis – New Product Release – PTCTNFMMFxxS

We are excited to announce the release of a brand-new Coaxial Arrestor design, the PTCTNFMMFxxS series of compact GDT arrestors.  Just like other examples of NexTek’s compact arrestor options, this unit is perfect for chassis-mount applications where space is at a premium…But at the same time, it provides heavy duty, military grade protection for your equipment and will not cost much more than a high-quality connector!

If you are looking for coaxial protection that does not cost you any more space and weight than absolutely necessary, perhaps because you’d prefer to integrate protection into the Radio Chassis itself, then you really have to check out this new design!

The PTCTNFMMFxxS-series coaxial arrester provides effective protection in an extremely compact form factor, and MMCX connectors for the lowest-profile connection.

PTCTNFMMFxxS OutlineAvailable with a TNC (f) bulkhead and MMCX (f) connectors, in a range of Protection Voltage/RF Power ratings.  See below and explore the datasheets to learn additional details!


Features:

  • DC to 6GHz Operating Band
  • Excellent Response and Residual Energy Reduction
  • Compact TNC to MMCX Bulkhead Protector
  • Low VSWR and Insertion Loss
  • Multi-strike, Rugged and Waterproof
  • Available in Multiple Protection Voltages: 90, 150, and 230V
