Wilson Electronics Lightning Surge Protector (859902), N-Female (50 Ohm)

Easy to install, good insurance to static charge problems around lightening strikes. This will bleed off a static charge or near strike and save your amplifier. It will blow out completely if hit directly and may save your system, but with direct strikes you rolls your dice and you take your chances.To greatly improve your chances install this system in line with your antenna close to the antenna with the cables going directly down to the surge supressor and the ground wire (little fitting on top in the photo) going straight down to the ground. I will drive a short rebar or attach to the com ground rod on a cable system. The trick is to mount the device so that it is with the ground fitting on the side and the threaded parts pointing straight up and down. Lightning does not like to turn, it wants to go straight to ground. So if you have little or no bending of the coax from the antenna to the surge unit, and little to no bending going straight to ground the unit most likely will take a major hit with no problems.lightning can ignore a 90 degree bend in a ground wire to jump off and straight to ground down a wall, it is that picky. When it does that the ground wire goes to a very high potential to ground for a micro second, enough to cancel a lot of the surge protection. Mount it vertical with a straight to ground as possible ground wire and you should be fine.The WeBoost amps are very sensitive receivers, they really should be protected. Most Sat Tv systems are installed with protectors, but not as good as this one. This one is top quality and functions much better than most on the market.

If you are putting any antenna on the outside of your house or any other building you need a Lightning Arrestor, which is what this product is.To be clear, these do not protect against a direct lightning strike, but they do protect against the electromagnetic energy that is generated when a lightning strike occurs in the vicinity (within a few miles radius) of the antenna. A direct lightning strike will destroy the antenna and the electronic equipment with or without an arrestor.A lightning strike in the area of an antenna produces a large electromagnetic field that the antenna picks up and converts to electrical energy which is then transmitted down the coax cable to the electronics in the amplifier. Without an arrestor the electricity produced by the strike can burn out components in the electronics.This is a 75 ohm lightning arrestor and should be used with 75 ohm coax and 75 ohm antennas. The arrestor has female "F" connectors, which are the common coax connectors used for television antennas and cable TV. If you have a 50 ohm booster system do not use this product - a 75 ohm arrestor on a 50 ohm system will cause a large signal loss and defeat the purpose of the booster.These arrestors are easy to install, just connect the antenna coax to one side and another coax to the booster on the other side. Then connect a ground wire to the ground terminal on the arrestor and run it to a ground rod or to your cold water pipe were it enters the building, whichever is closer (it's important to keep the ground wire as short and direct as possible).I got this to go with  Wilson Electronics - DB Pro - Cell Phone Signal Booster for Large Home or Office - Includes Directional Antenna  from Amazon and the system really does work. See my review of the booster system on that webpage.

Wilson quality, great design, easy install that should go outside so the ground can run free of the structure. Plan for the connection when you design the antenna install. Have a line from inside antenna to amp. Have a line from the amp to the outside mounted Lightning Surge Protector and another line from the surge unit to the outdoor antenna. Order a replacement gas cartridge for the surge unit. Lines with factory ends will be far better than anything you try to invent at home. I used wilson 30ft,10ft and 2ft cables. The longer the wire run, the more signal is lost. Note: I used #8 solid copper ground line for connecting to a utility copper grounding rod driven six feet into the ground. Big Box hardwares have these items in the electrical depts.

The device is heavy duty. Constructed of good quality material but finding connectors to fit RJ6 coaxial was difficult to do.

A pretty simple device, but hard to rate it until lightning strikes. I live in South Florida, an area with a very high risk of lightning strikes. The device is well finished with absolutely no instructions on how to install it. You will need to connect it with a heavy wire to your ground rod. I installed a new ground rod as my antenna installation was far from the existing ground rod. Be sure to order the correct lightning suppressor. Most Wilson setups require the 75 Ohm suppressor. It is easy to order the incorrect item.

Was operating a internet over cell tower setup without one of these when EM from a heavy storm nuked some of my equipment; now with this item that doesn't happen anymore.Connectors are female N type connectors on both sides so get extra cables accordingly. Will also require some wire to attach to the grounding lug and to jab into the ground. For a cheap grounding spike you can go to a hardware store and buy a big foot-long galvanized nail for under a dollar and wrap the other end of the wire around it. Solder the wire ends in place to ensure proper conductivity.For anyone needing replacement fuses, according to a bit of Google research the fuse part for this product is called a "Wilson replacement gas discharge element 859920"

is very good

Not much to rate - it's exactly what I ordered and met my expectations.

expensive but worth it.

Work just as discribed...would buy it again

Compact, but needed adaptor to function.served the purpose for antenna.Surge protector
