7.0 Antenna Mounting and Tower Specifications
The Horizon Compact unit clip mounts onto a range of antennas, providing a variety of gain and range
options. The same mounting system is used for all sizes of antenna.
The Horizon Compact has four, integral, spring loaded, mounting clips. The antennas are provided with
four mounting lugs, onto which the mounting clips attach. The antenna port and the waveguide adaptor of
the Horizon Compact, push fit together before the clips are set, and are weather-sealed with a lubricated
‘O’ ring located on the outside surface of the antenna port (lubricate with provided lubricant before
assembling).

7.1 Polarity
Horizon Compact units that operate on licensed radio bands use a diplexer system to simultaneously
handle transmitted and received signals to/from the antenna. In this case, both transmit and receive
antenna elements must have the same polarity.
For unlicensed radio band units, an orthogonal mode transducer (OMT) is used to allow the radio to
simultaneously transmit on one polarity and receive on the opposite polarity.
7.1.1 Licensed Radio Bands
Both Horizon Compact units must be mounted on the pole/tower oriented for the same polarization. i.e.
both vertical polarization, or both horizontal polarization.
Caution
Cross-polarized radios or antennas result in the signal strength being 20-
30 dB below expected RSL levels! Ensure both radios have the same
orientation (vertical or horizontal ).
