The sealed shunt coil are available for both our 80 meter antennas, the SA-680S “shorty” and the SA-680 that sports # 10 gage wire coil.
Our shunt coil comes installed in a gasket sealed polycarbonate enclosure manufactured by Bud Industries. This allows for a very quick and easy install onto the Scorpion antenna.
These work great for autos and our customers that haul material in the bed of their trucks, providing excellent damage resistance.
The SA6-160 our “160 meter” antenna is supplied with an 8 and 16 turn shunt coil that is switched through a relay. Shunt coils and relay are enclosed in a water tight polycarbonate BUD enclosure mounted at the base of the antenna.
We do supply, through special order, custom wound shunt coils for your most demanding antenna project. Please contact us directly for tech support and your requirements.
