3.6 Antenna and Radio Installation
It is critically important during installation to ensure the
radios on each side of the link are in the same polarization
(horizontal­horizontal or vertical­vertical). 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.
It is also critically important that a high­band radio is paired with
a low­band radio to ensure the system will operate properly. Prior
to installation check each radio to verify one is a high­band and
the other is a low­band version. The label on the radio will
indicate the band (blue for high or red for low).
1. Install antenna and radio:
The first letter of the designated polarization is
stamped onto each unit to identify orientations
when the polarity mark is positioned on top:
“H” for horizontal.

polarity
2. Verify that the four (4) captive 3/8­16 bolts with
lock and flat washer are in place.
It is important that all four bolts are tightened
evenly (hand tight, 1 to 2 turns each until the
lock washer is flattened).
Units have captive bolts attached to the radio
housing. A 9/16­inch open­end wrench is
required to tighten them.
Units have captive bolts attached to the 2’
antenna. A 1/2­inch open­end wrench is
required to tighten them.
“V” for vertical polarity.
