www.alphadeltacom.com UL LISTED Certified protection for your equipment from 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 are running 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 weather proofed by the use of O-ring seals and all hardware is stainless steel. Wide Frequency Range: DC thru 3 GHz, much wider than narrow band DC blocked or stub designs. Low Insertion Loss: 0.1dB 1 GHz, 0.2dB 2 GHz, and only 0.5dB 3GHz, typical.

Convenient limited space installation requires only 60 ft. of space for amazing DX performance with the feed-end at 35 ft. and the low end only 8 ft. above ground ... $80.99 Effective Atmospheric Surge Voltage Protection D angerous static charges measuring 1000s of volts can be developed from local thunderstorms, high wind driven snow or sand; so potent they can actually puncture the dielectric of coaxial cable. Solid-state transceivers and other equipment in your hamshack are very vulnerable to these high-voltage charges so you should take every precaution to protect your equipment and shack from possible serious damage and ALPHA DELTA has the answer! Special Arc-Plugs are used in ALPHA DELTAs Coax Switches, Surge Protectors and DELTA-C Center Insulator which bleed off slow rising static electricity charges from the feed line, routing them harmlessly to ground. This is far more effective than DC grounded baluns or chokes. But, even as effective as these devices are, you still need to do a good job of proper grounding as outlined in the ARRL Handbook, etc. Alpha Delta ISO-RES inductors replace lossy traps and capacitors, rated Full Power. Direct 50& coaxial feed, no tuner required except for extended frequency coverage. Factory assembled with insulated #12 copper wire, stainless hardware and 50 ft. of nylon rope.
