CO-LOCATION OF EASYREACH LINKS
It is possible to operate up to three EasyReach links with antennas mounted on
the same mast. The antennas must be mounted so they do not interfere with
each other. The following measures minimise interference:
•
Frequency Diversity.
The Plessey EasyReach is factory fitted to operate on one of two channels
within the ISM band. Where more than one link is required, one link should
be selected to use a different band from the other link(s).
•
Space Diversity.
Interference may be minimised by locating antennas from different links as
far as possible from each other. In the case where the antennas are
mounted on the same pole or tower, they should be separated as much as
possible, particularly if they are not pointing in opposite directions.
•
Polarisation Diversity:
The antennas may be mounted so the antennas from one link are mounted
with a different polarisation to the antennas from another link. This is
especially important in the case where three links are used, since two links
must share the same frequency band.
