Sideband Antenna Installation
The sideband antennas must be mounted on a radius of 22 feet from the center of the counterpoise and evenly
spaced at 7.5° intervals. They must be uniform in height and at the same height as the carrier antenna which is
mounted at the center of the counterpoise. There are two methods used in locating the sideband antennas on the
counterpoise mounting rail: the theodolite method and the tape measure and spirit level method. The theodolite
method is the preferred method. Refer to Section 9.4 of the Model 1150A DVOR Antenna Operations and
Maintenance Manual (570002-0001) provided with the 470165-0003 Antenna Kit.
