Figure 24 Two ODUs and antenna mounted on a coupler
Direct mount dual-polar antennas
Applies to ODU deployments only.
Direct mount dual-polar antennas are only used in 2+0 cross-polar direct mount
configurations. They are supplied with an orthogonal mode transducer (Figure 25) with
transitions (vertical and horizontal) that allow two ODUs to be coupled to the antenna.
Cambium supply dual-polar direct mount antennas as listed in Ordering antennas on page
2-59.
However, if a previously purchased antenna is to be upgraded to support a 2+0 cross-polar
direct mount configuration, Cambium can supply separate orthogonal mount kits (OMKs),
as listed in Ordering OMKs on page 2-90. The OMK can only be fitted to an antenna that is
in the same band, for example, a 6 GHz antenna can only accept a 6 GHz OMK.
