BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - INSTALLATION
The PRC-4090 manpack can be used with the 10 metre throw over long-wire
provided or the optional 3 metre collapsible whip.
Note: Either the whip or the long-wire can be used but not both together.
Collapsible Whip Antenna (P/N 4090-02-07)
The gooseneck is fitted to the whip antenna stud and the whip to the goosneck
by bayonet fitting. The whip antenna should then be unfolded to its maximum
height. If using the Barrett manpack while walking in the backpack configura
-
tion it is suggested that while in receive standby mode the collapsible antenna
be only extended to half height and secured using the Velcro tab. When a call is
received extend the antenna to full height before transmission.
When using an un-tuned antenna such as the whip or the long-wire the selec-
tion “Antenna Type” (see page 24) in the standard menu should be used to
enable the automatic tuner i.e. select “Whip/Long-wire” operation. When this is
selected the in-built tuner automatically tunes the whip or long-wire whenever
the unit transmits after a channel change.
Note: Do not use the whip antenna near metallic structures. This can produce high
voltages within tuner and may cause damage.
