WSI AV-300/350 Installation Manual
b)
The satellite antenna should be mounted so that it is within 15
°
of level when the aircraft
is in straight and level flight.
c)
The satellite antenna should be located 36 inches or more away from the nearest
transmitting antenna.
d)
The AV-300/350 satellite antenna requires a ground plane to achieve optimal
performance. Metal aircraft should have a good bond between the airframe and the AV-
300/350 antenna to provide an adequate antenna ground plane. Satellite antenna
installations on composite aircraft require the installation of metallic foil strips, to the
inside of the aircraft, to provide the antenna ground plane.
e)
The satellite antenna should have a clear (no aircraft obstructions) line-of-sight view of
the sky above 60 degrees of elevation.
f)
See Satellite Antenna Installation on page 43 for additional information.

Use the following guidelines to ensure a suitable placement for the AV-350 remote control
antenna:
a)
The remote control antenna cable should be at least 18 inches long.
b)
The remote control antenna must be mounted inside the aircraft.
c)
The remote control antenna should be located to maximize reception from the remote
control. First determine all locations within the aircraft where an occupant may utilize
the remote control, and then position the antenna so that it has reliable reception from
those locations. The antenna may be able to receive signals through non-metallic objects
and surfaces; however metallic or electrically conductive obstructions should be avoided.
d)
The remote control antenna may be mounted to metallic structures; however poor
reception may result at locations where the mounting surface obstructs the view of the
antenna.
e)
Avoid locating the remote control antenna inside the cabin within 12” of any external
antenna, especially in composite aircraft or other aircraft with non-metallic skin. If it is
necessary to mount the remote control antenna within 12” of an external antenna be sure
to carefully evaluate the AV-350 and the system associated with the other antenna for
possible RF interference.
f)
The AV-350 receiver may be mounted prior to mounting the remote control antenna so
that candidate locations may be evaluated. It is a good idea to evaluate the proposed
location both before and after permanently affixing the antenna.
g)
The remote control antenna may be mounted in any orientation for optimal performance.
h)
See Remote Control Antenna Installation on page 46 for additional information.
