|The case is a Doskocil brand watertight
equipment case. The video goggles are for RPV flight. The LCD
monitor is used to monitor a second video channel, either from a second
camera on the same plane, or from a camera on another plane. The
12v battery powers all ground based equipment except the camcorder, which
is running on it's own battery. The microphone allows me to maintain
audio documentation of the day's flight. It is captured on the right
audio channel of the camcorder.
|A detail shot of the antenna boom shows
how I mounted the two receivers using 3/4 pvc pipe and various fittings.
The cables are routed through the pipe to keep the installation clean.
Note the additional audio channel on the right receiver. A lapel
mike plugs into the receiver and allows me to capture one channel of audio
from the air, and one channel of audio from the ground.
|With two receivers I can do a real time
'antenna shoot-out', monitoring the performance of two different antenna
designs by setting both receivers to the same channel. The receiver
arms are articulated and allow me to position the antennas for best reception.
Power is fed to the receivers from the main groundstation battery.
|The antenna boom can be broken down for
travel. The receiver arms are folded up to minimize the space they
take up, without having to remove them from the boom.
