Telemetry and/or Differential Antenna (if option installed)
Overview
As the Telemetry/Differential antenna has to view the ground based broadcast antenna, the antenna should be
outside the aircraft and have visibility of this base antenna.
Placement
The ideal location for this antenna is on the bottom of the helicopter and as vertical as possible with the following
considerations:
Keep away from other communications antennas as far as possible.
Do not mount immediately next to gear struts of hook assembly
The shorter the coax the better the range.
