Mounting the Antenna

Mounting the Antenna

This section includes requirements and mounting guidelines for the RoamAbout outdoor antennas. Each antenna mounting section contains an illustration of the antenna, component description, and a mounting procedure.

Selecting a Mast

Note: You must supply your own mast on which to mount a RoamAbout antenna. RoamAbout antennas do not come with masts.

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.

The mast must satisfy the following requirements:

•The mast must be constructed of sturdy, weatherproof, noncorrosive material such as galvanized or stainless steel construction pipe.

•Mast diameters for each antenna should be as listed in Table 3‐2.

•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.
