Lightning arrestor N Female to Female 50 Ohm Lightning Surge Protector with 90 V Gas Tube DC-3GHz

Good product

Unless you have a lightning strike, you will never know if this lightning arrestor works or not. I use mine in the cable to a horizontal end fed wire antenna, and the unun transformer really grounds the center conductor (as far as dc goes) so this lightning arrestor is the suspenders in my belt and suspenders transceiver protection. In 30 years I have never even had a nearby lightning strike, so now I've even gotten so complacent that I don't disconnect the coax from my transceiver during thunderstorms. That may ultimately be a problem, but the lack of nearby lightning strikes in 30 years or so seems to indicate that my location doesn't have a lightning problem. I know, it only takes once to wipe out a $1000 transceiver, but I've really gotten lazy! Regardless of your location, however, I would have one of these in the coax between your antenna and transceiver, just in case the worst happens. Oh, and maybe even disconnect your transceiver too if you are in an area having frequent lightning strikes.

Seems to be well built, especially considering the price. I measured good VSWR thru UHF. Will it work to suppress transients? No way to know. Only a professional testing lab could tell. If nothing else, this will provide shield grounding. Note that to be effective, it must be connected to a low impedance ground (the transient needs somewhere to go). It ideally should be mounted on the outside of the building near where the coax enters the structure and connected directly to ground. Best way is to attach it directly to a ground rod bonded to the building ground (see attached photo). The gas tube in this type of suppresser will eventually fail after a number of transients. It should fail shorted and will need to be replaced. So, if your antenna stops working, first replace the gas tube before questioning the suppressor.

Until we get a rambunctious lightening storm, it is really impossible to rate this arrestor's ability to protect my $1000 cell booster. We get those several times a year, but I think we are now past that time of year. However, this device was as described. The ends were type N female connectors that connected to my cable just fine. The gas discharge is a very well known technology. So unless they cheaped-out and did not put in the gas, there is no reason that this should not work exactly as it is designed to work. It was a good value. I used a 10 gauge copper wire to ground it. My main copper ground wire is a long heavy duty battery cable that grounds to the metal frame of the house and to a 6' copper ground rod. That should take a pretty good lightening hit before vaporizing. Only time will tell.

installed this when installing antenna. easy install don't know if it works and hope never to find out

Product picture is misleading. Only comes with one......

I hope I don't have the opportunity to test these, but they use proven gas-tube technology so I'm confident it'll work.They feel solid and are well machined.I now have several of these, because at this price point I'll buy many more than if they were $75.I have two of these on one antenna setup, one at the antenna mast, where it goes underground. The other is at the ground plate, where it comes into my house. (see photos)I will be buying more of these as I install new antennas.
