BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - INSTALLATION
Antenna Assembly
Mounting the Base Spring
The base spring should only ever be hand tightened, if a tool is used it may
damage the spring base.
Mounting the Whip Sections
To mount the whip sec-
tion it is recommended
that only one section of
the whip is screwed onto
the antenna at a time.
The whip section should
be hand tightened, then
a suitable tool (i.e. a
spanner) can be used
to tighten the section a
further 10 to 20 degrees
clockwise while holding
the antenna body with a
free hand.
