Basic Installation
BreezeACCESS/MMDS Series 5 SU-I/ID Installation Manual
When installing a single antenna, modify the transmit diversity option to either
antenna 1 or antenna 2, according to the antenna being used.
2.4.4 Antenna Polarization
Antenna polarization must be the same at either end of the link. In most
applications, the preferred orientation is vertical polarization. Above-ground
propagation of the signal is better when it is polarized vertically. To verify
antenna polarization, refer to the assembly instructions supplied with the antenna
set. For screw-on and detached omni antennas, make sure that the antennas are
extended upward vertically in relation to the floor to achieve vertical
polarization.
2.4.5 Antenna Seal
When using outdoor antennas, you must seal the antenna connectors against rain.
Otherwise the antennas are not suitable for use in outdoor installations.
2.4.6 Lightning Protection
Lightning protection is designed to protect people, property and equipment by
providing a path to ground for the lightning’s energy. The lightning arrestor
diverts the strike energy to ground through a deliberate and controlled path
instead of allowing it to choose a random path. Lightning protection for a
building is more forgiving than protection of electronic devices. A building can
withstand up to 100,000 volts, but electronic equipment may be damaged by just
a few volts.
Lightning protection entails connecting an antenna discharge unit (also called an
arrestor) to each cable as close as possible to the point where it enters the
building. It also entails proper grounding of the arrestors and of the antenna mast
(if the antenna is connected to one).
The lightning arrestor should be installed and grounded at the point where the
cable enters the building. The arrestor is connected to the unit at one end and to
the antenna at the other end.
