Aligning The Transmitter And Receiver - Derytech Shepherd User Manual

4.3 Aligning the Transmitter and Receiver

Correct alignment of the antennas is critical for achieving optimum performance and transmission distance. The
longer the wireless video transmission range, the more important the alignment of the antennas becomes. For ranges
of over one kilometer, correct alignment is measured in only a few degrees, both up and down, and left to right.
Consider using a Global Positioning Satellite (GPS) handset to determine the Transmitter and Receiver angles
accurately (using a GPS system allows a 10 Kilometer range to be aligned faster and more accurately than a 1
Kilometer range aligned "by eye").
NOTE: When aligning the Transmitter and Receiver, hold the units in each adjusted position for
at least 3 seconds before checking the resulting signal / picture, as the system requires a short
time for the processing and transmission of the digital signal.
NOTE: After alignment has been completed, tighten the bolts so that the units are secure and
will not move in a strong wind.
