The following parts are required for adjustment
1. Antenna connector adapter
The antenna connector of this radio uses an SMA termi-
nal.
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.)
2. Jig (chassis) for adjustment(part number A10-1392-03)
■
Use the jig as follows:
1. Insert the coaxial antenna connector into the jig.
2. Place the unit on the jig and fi x it with 12 screws
q
.
3. Solder the antenna terminal to the terminal of the unit.
Note:
Supply power from an external power supply.
