Lightning Arrester UHF PL259 SO239 M to F 0-3GHz DC-230V (Surge Protector) 100 watts
The Opek A7516 Lightning Arrestor is not the "state-of-the-art" in radio protection. These "air gap" arrestors were OK for tube sets, but are not the best for today's solid-state rigs. However, if you are on a budget, this device is a whole lot better than nuthin!
As with all lightning protection devices; you must connect it to an earth ground with thick ground wire, and it is not going to provide protection in the event of a direct hit. It may be used for receive, or transmit to 100 watts. SO239 input and PL259 output.
