Alpha Delta DELTA Series Surge Protected Coax Switch 
(all models include replaceable Model D-4 gas tube ARC-PLUG (tm) surge protector, built-in - 4-Position, SO-239, 500Mhz

Power Rating: 1.5 KW
Impedance: 50 Ohms

DELTA-4

SWITCH POSITIONS     Four, two either side of the “common” center, connector.

LIGHTING 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 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 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 the point of ground hardware connection to the base plate. It is also good practice to ground the coax shield at the point of entry to the building.
