This section includes requirements and mounting guidelines for the RoamAbout outdoor
antennas.

Requirements for the Directional and 7 dBi Omni-Directional Antennas

To minimize the influence of obstacles, signal interference or reflections, install the
antenna at least 2 meters (6 feet) away from all other antennas.
If you need to mount multiple antennas on a single mast, alternate the mounting of
directional antennas for vertical and horizontal polarization
In subfreezing conditions, the communications link could fail if an antenna is exposed to
ice buildup or covered with snow.
A mast (not provided) must satisfy the following requirements:
The mast must be constructed of sturdy, weatherproof, noncorrosive material such as
galvanized or stainless steel construction pipe.
Mast diameter should be between 35 mm (1.4 in.) and 42 mm (1.6 in.).
Antenna mast length must be sufficient to allow an antenna height at least 1.5 meters
(5 feet) above the roof peak. If the roof is metal, the antenna height should be a
minimum of 3 meters (10 feet) above the roof.
