up to 100 km (60 mi), using frequencies of
3–30 MHz.
The 3 m (10 ft) collapsible whip antenna is
suitable for communication over short to
medium distances up to 500 km (300 mi), using
frequencies of 2–30 MHz.
Deploying a tactical whip antenna
To ensure optimal transceiver performance and
to avoid exposure to excessive electromagnetic
fields, the antenna system must be deployed
according to the instructions provided.
To deploy a tactical whip antenna:
1Straighten the antenna.
1Switch off the transceiver.
1Screw the antenna onto the antenna stud ( )
on the front panel.
1Orient the antenna vertically for medium-
distance communication on any suitable
frequency, or horizontally for short-distance
communication on frequencies less than
approximately 6 MHz.
1To use an earth lead:
• Plug the earth lead into the earth terminal
( ) on the front panel.
• Clip the other end of the earth lead to a
large metal object, e.g. shed, vehicle,
fence post.
1To use a counterpoise:
• Lay out the counterpoise, forming a
cross.
• Prop the transceiver against a suitable
support in the centre of the counterpoise.
• Plug the wire from the counterpoise into
the earth terminal ( ) on the front panel.
1Switch on the transceiver.
1Select a channel, then press PTT to tune.
1Ensure that the internal antenna tuner is
activated ( ATU/50 or ATU).
NOTE
Select a site that is clear of
overhead power lines and other
electrical interference.
WARNING Do not deploy or use the antenna if
there is lightning in the area.
WARNING Take care not to cross the
thread on the antenna stud.

High RF voltages are present
during transmission and tuning. Do
not touch the antenna during these
activities.
WARNING
You should not transmit from your
transceiver or tune the antenna
unless people are standing beyond
the safe working distance of 0.6 m
(2 ft) from the antenna.
