Antenna must have a sufficient power handling capability (400 W), and low SWR value

of 1.5 typ., 1.8 max..

‡J ACC (Remote Controller Connection Terminal)

This is a DIN socket for connecting the remote head (HRC-60, optional parts), which

enables turning on and off of the power as well as monitoring various operation status in

a remote location.
