WHIP ANTENNA LOCATION AND MOUNTING
3.5-1
The POINTER SENTRY 4000-10 Whip Antenna and coaxial cable are provided to permit external antenna
radiation. Use ONLY the cable furnished with the unit. Whip antenna should be mounted as far aft as possible on
the surface of the aircraft (or helicopter) as this area is normally less susceptible to impact damage.
Pay particular attention to the following:
(a)
Mount Whip Vertically on the upper surface of aircraft (or helicopter).
(b)
Locate so as to minimize RF coupling from adjacent communications antennae. Maintain maximum practical
distance from all other antennae.
(c)
Must not foul other antennae when whipped in flight.
(d)
Mount Whip antenna as close as possible to transmitter. Neatly coil and tie any excess in the 5 foot coax cable.
NOTE: COAXIAL CABLE MUST NOT BE CUT OR ALTERED.
