The OPEK AT-7516 Coaxial Static Arrestor is an "air gap" arrestor. If you are on a budget, this device is a better than doing nothing. As with all such protection devices, you must connect it to an earth ground for it to work correctly. It has UHF-Female (SO-239) connectors. The arrestor is rated to 500 MHz Max. Power rating: 1500-Watts (PEP) for frequencies below 60 MHz. Few, if any, arrestors can withstand a direct lightning strike; however, when installed properly arrestors can help prevent costly repairs to sensitive radio equipment due to high energy transients from nearby lightning strikes. A metal link opens in the presence of excessive energy giving those surges a direct path to ground, thus protecting your equipment. The arrestor is designed with a rugged nickel plated brass housing and UHF connectors.
Disconnect the coaxial connector at your base antenna, install the arrestor and reconnect the coaxial cable. Run a #6 or #4 (preferred) copper ground wire from the connector housing to earth ground. The ground wire offers a low resistance path that will allow atmospheric static and electrical charges to be totally or partially discharged to earth ground.
For best results, we recommend that the ground wire be at least #6 guage copper and that the connector is soldered to the wire to protect against corrosion causing resistance. Also, for best results drive a ground rod into the earth several feet. Copper ground rods are readily available at most home improvement stores or farm supply businesses.
OPEK Communications also makes a quality line of Gas-Arc surge protectors / lightning arrestors for improved protection.

Works as they are advertised.
I like the product. It came rather fast. So, I can get my project finished. Thank you very much!
Seems to work well with the right ground wire.
As stated it's better than nothing. Put at base of antennas outside and wrapped accordingly one #8 common ground from each to an 8-foot ground rod... works great fast shipping thanks.
American Radio Supply is an excellent company with competitive pricing! The Coaxial Lightning Arrestor I was sent was double-packaged and came in great condition!
I have checked out a few of this style lightening arrestor and pleased this was my choice. Very easy to install at the bottom of the tower and should be easy to re-install if a strike does occur. Small price to pay for insurance.
Very good lightning arrestor. Of course I have not had a strike to really put it to the test. Easy to install on the bottom of the antenna.
I'm well satisfied with this product
