Alpha Delta DELTA Series Surge Protected 50 Ohm 2 Position Coax Switch with TNC Connectors
Power Rating: 1500W PEP/CW
Impedance: 50 OHMS
Connectors: TNC
Lightning Surge Protection: Alpha Delta Model D-4 internally mounted, field-replaceable ceramic gas tube Arc-Plug Cartridge Pill
Special Switching Functions: When the knob points to the center(ground) switch position, all antenna circuits are internally disconnected and grounded. When the knob is in the active position, the unused antenna ports re grounded. Then active position circuit is continuously protected by the Model D-4 Arc-Plug Cartridge Pill.
Grounding Requirements: A separate, external ground wire must be used from one set of user supplied 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 hardware connection to the base plate. it is also good practice to ground the coax shield at point of entry to the building.
