3.6 Radio Installation
1. Place the radio in the yoke—the two up/down pivot bolts should rest in the U’s cut
in the yoke.
Note that when the radio comes from the factory, the mounting plates are in the
vertical polarization position, that is, the diamond marking on the radio (see insert
below) on the front of the radio housing is to the right when viewed from the front.
For horizontal polarization, the mounting plates should be moved so that the
diamond is at the top when viewed from the front.
Figure 3-5: Polarization diamond orientations: horizontal (left) and vertical (right)
Note: The blue color label indicates a high band radio and the red color label
indicates a low band radio
See Figure 3-5 for further explanation and visual image of horizontal vs. vertical
polarization.
CAUTION!
It is critically important during installation to ensure the radios on each side
of the link are in the same polarization (horizontal-horizontal or vertical-
vertical). A link that has a radio on one side of the link set in the horizontal
polarization and the other side of the link set in the vertical polarization will
not operate properly.
Further, it is also critically important that a high-band radio is paired with a
low-band radio to ensure the system will operate properly. Prior to installation
check each radio to verify one is a high-band and the other is a low-band
version. The label on the radio will indicate the band (blue for high or red for
low).
