Switch Positions Two, one either side of a 'common' centre connector.
Lightning Surge Alpha Delta Model D-4 internally mounted, field replaceable ceramic gas tube
Protection ARC-PLUG Cartridge Pill.
Special Switching When the knob points to the centre (Ground) switch position, all antenna circuits
Funtions are internally disconnected and grounded. When the knob is in an active position,
the unused antenna ports are grounded. The active position circuit is continuously
protected by the Model D-4 ARC-PLUG Cartridge Pill.
Grounding A separate, external ground wire must be used from one set of user supplied
Requirements mounting hardware (through either thru-hole on the base plate) to the station ground
system (not the equipment chassis). The ARC-PLUG Cartridge Pill will not
operate without a good ground. Note: Paint should be removed at point of ground
hardware connection to base plate. It is also good practice to ground the coax
shield at point of entry to the building.
