6. Start the patrol vehicle and position the A/C - heater
fan to a mid-range speed. Move the antenna/mount to
different positions on the windshield while listening to
the audio. If there is fan interference, the audio will
have a raspy sound instead of just noise. Position the
antenna to minimize the amount of fan interference.
1. Aim of the antenna:
Stationary: Maximum performance of the system will
be achieved when the antenna is aimed
directly toward the vehicles being
monitored.
Moving: Aim the antenna parallel to the ground
and straight down the roadway.
NOTE: The polarization of the Raptor RP-1 K-Band
antenna is linear. For best results the antenna
must be mounted with the aim site on the housing
at the top or bottom, not to the side.
