antenna is selected and defaults to bypass when the tuner is off or DC power is removed.

•

Ant 1:

Connect a secondary 50 ohm antenna coax feedline to this SO-239 connector.

•

Gnd (wing nut):

Connect to the antenna system ground.

•

Tx:

Connect a 50 ohm jumper coax from this jack to the ANT jack on the rear of the

transceiver.

•

Radio:

(optional) Connect the optional IC-PAC Icom or Yaesu radio interface cable to a

supported ICOM or Yaesu radio.

•
