Site Considerations
One of the first installation considerations is where to locate the
Gateway. The first priority in choosing a site is selecting a line-
of-sight location not obstructed by trees, hills, mountains, or
anything else that would block the RF communications from the
MIUs in that area. The Gateway can be installed on top of a
building so that it is set higher than the MIUs it is reading. If a
rooftop installation is not feasible, the Gateway can be installed
on a pole ranging from 2 inches to 16 inches in diameter.
Do not mount the Gateway, antenna mast, or antenna to
a pole or similar structures carrying open electric light,
power wires, or trolley wires over 250 volts between
conductors. (See NEC, Article 8.10). See Appendix A.
The Gateway mounts easily to a wall. However, for an indoor
wall-mounted unit, you need to choose a location that is easily
accessible and in close proximity to where the antenna mast can
be mounted outdoors.
RF propagation should be conducted prior to site selection to
ensure adequate RF communications.
The antenna should have, at the minimum, 10-feet vertical
separation from other antennas to minimize the interference
between the systems. Locations that must share space with
multiple transmitting systems may require additional
equipment to protect the systems from interfering with each
other. See Appendix C.
