Mounting the RF Antenna and Antenna Mast
The RF antenna mast and stand must be grounded to the
same grounding electrode used for the building's
electrical system to ensure that all exposed, non-current-
carrying metal parts are the same potential (refer to NEC
Article 810).
Antenna contact with high voltage wires may result in
death. Watch for overhead electric power lines when
erecting the antenna and mast
.
Do not mount the antenna, antenna mast, or Gateway on
utility poles, electric service masts, or other structures
carrying open electric light or power wires, or trolley
wires of over 250V between conductors. Coaxial cable
must maintain clearance of at least 2 feet (.61 M) from
power or light wires of less than 250V, or at least 10 feet
(3.048 M) from power wires of more than 250V, in
accordance with NEC Article 810, CEC Section 64.
When mounting the RF antenna and antenna mast, it is
important to maximize the line-of-site relationship between the
RF antenna and R900 MIUs for optimum RF communications.
