3.2 General Guidelines
While the setup of the TA-8 link is very simple, observing a few
considerations will help get the optimum performance.
First, height of the equipment plays an important role in the distance
over which the radio link works. The higher you place the TA-8, the
longer the available link range. Please use proper judgment of safety
when following this advice, especially for mobile applications.
For any rf signal, having metal objects near the receiving or
transmitting antenna will severely affect the performance. With this in
mind, avoid placement in any location that has large metal structures
or objects that hinder a good LOS to the transmitter. The TA-8 being
a microwave receiver, trees and buildings are also an obstruction to
signal reception.
The radio link must be configured correctly and the equipment
chosen to meet the required range/ distance. Choice of transmitter
amplifier, output power, type of antenna etc. is governed by
considerations such as battery power on the UAV/ airplane, antenna
height allowed, cooling for transmitter etc. If you need assistance,
please call Avalon RF Engineering at 619-401-1967.
