■ Antenna connector adapter
The antenna connector of this transceiver uses an SMA
terminal.
Use an antenna connector adapter [SMA(f) – BNC(f) or
SMA(f) – N(f)] for adjustment. (The adapter is not provided
as an option, so buy a commercially-available one.)
■ DC supply
BATT+, BATT–: External power supply terminal (Fasten it
with an alligator clip.)
