Alpha Delta ATT-3G50U-HP

Lightning Surge Protector 0-500MHz; 2000W; UHF (SO-239)

Outstanding protection for your equipment from the effects of lightning and static charges. Much more effective than low-cost air-gap types. The heart of this protector is an easily replaceable Arc-Plug - two electrodes hermetically sealed in a gas filled ceramic cylinder. Acting like a voltage dependent switch, the Arc-Plug can repeatedly carry large currents to ground for brief periods. If you need to run control voltages through the coax, the impedance compensated thru-line cavity design allows it to pass thru instead of having to "wire around" as with some other DC-blocked designs. All models are completely weatherproof by the use of O-ring seals and all hardware is stainless steel.
