PANEL DESCRIPTION
!1
ANTENNA CONNECTOR 1 [ANT1]
!2
ANTENNA CONNECTOR 2 [ANT2] (pgs. 13, 14)
Accept a 50
Ω
antenna with a PL-259 connector.
NOTE: When using an optional AH-3
HF AUTOMATIC
ANTENNA TUNER
, connect it to the [ANT1] connector.
The internal antenna tuner activates for [ANT2] and
deactivates for [ANT1] when connecting the AH-3.

ACC SOCKETS
!3
GROUND TERMINAL [GND] (pgs. 13, 14)
Connect this terminal to a ground to prevent electri-
cal shocks, TVI, BCI and other problems.
