13.4 Antenna Location, Spacing, and Mounting
Consider the following points regarding RLX2-IHx series radio antenna location, spacing,
and mounting:
When placing antennas, ensure a clear line of sight between the Master radio's
antenna and all of the other radio antennas.
If the site contains obstructing terrain or structures, mount the antenna on a tower or
rooftop to provide a line-of-sight path. This line-of-sight consideration becomes more
important as the transmission path becomes longer.
Mount the antennas as high off the ground as is practical for greater range.
Mount the antennas away from massive structures. For example, radio signals
bounce off metal walls, which can compromise a clear signal.
Mount the antennas and install radios away from sources of RF interference.
Use the shortest possible antenna cable length. Signals lose power over the length
of the cable.
Choose antennas that are appropriate for the network's intended function.
If antennas are on radios on the same network, mount them with matching polarity. If
the antennas are on separate networks, mount them with different antenna polarity;
for example, mount one antenna vertically and the other horizontally.
Space radios at least three feet (one meter) apart so they do not overload each
other. If radio antennas must be near each other:
o
Mount omnidirectional antennas directly above each other.
o
Position directional antennas so they do not point at nearby antennas: place
antennas side by side if they point in the same direction; place antennas back to
back if they point in opposite directions.
