Mounting the RF Antenna and Antenna Mast
Mounting the Antenna Mast
Mounting the Antenna Mast to the Building
With a wall mount installation, it is necessary to mount the RF antenna
on the exterior of the building. Complete the following steps to mount
the antenna mast to the building.
1 Use antenna-pole brackets to install the pole to the building.
See Figure 54.
2 With a drill, pre-drill your holes for the first pole bracket.
3 Secure the pole bracket in one of the following ways:
• If mounting to a wood-constructed wall, use corrosion-resis-
tant wood screws rated at a minimum of 20 pounds loading.
• If mounting to sheet metal or masonry, use appropriate sheet
metal, corrosion-resistant screws, or masonry anchors rated at
a minimum of 20 pounds loading.
Figure 54 Securing Pole Bracket
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).
When mounting the RF antenna and antenna mast, it is important to
maximize the line-of-sight relationship between the RF antenna and R450
MIUs for optimum RF communications.
Antenna contact with high voltage wires may result in death.
Watch for overhead electric power lines when erecting antenna
and mast.
Do not mount antenna or R450 MC on utility poles, electric ser-
vice mast, or other structures carrying electric light or power
wires. Coaxial cables must maintain clearance of at least 2 feet
(0.61 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, per NEC Arti-
cle 810, CEC Section 54.
