Antenna Extension Cable
If antennas are to be mounted farther from the RTU than the 24” 12
-1545-0 or
72” 12
-0477-0 adaptor cables allow an extension cable will be needed.
Situations that may require an antenna extension cable include:
x
Mounting Base RTU antenna to roof
x
Mounting Repeater Antennas to towers with the Repeater located at the
foot of the tower for increased access
x
Mounting antennas for a cluster of remote mounted panels (multiple
directional antennas must be stacked vertically, not horizontally).
