Contacting an Antenna Installation Company

Contacting an Antenna Installation Company

Have an antenna installation professional install the outdoor antennas. The antenna installer provides the expertise to properly install, secure, and ground your antenna. The following describes tasks that the installer may need to perform.

NOTE

The antenna installation professional should be licensed or certified in accordance with local regulations.

Lightning Protection

Determine the mounting location for the lightning rod (positioned near the antenna).

Ensure an earth ground location for the antenna structure and lightning protector.

Mounting Requirements

Determine the type of mounting that is required (tripod, wall mount, etc.)

Determine the guy wires needed. Typically, three guy wires are needed for each 3 meter (10 foot) section of the mast; for example, 6 meters (20 feet) of mast requires six guy wires.

Line of Sight

Determine the mounting location for the antenna.

Ensure that the back of the antenna is clear.

Ensure that remote and local antennas can see each other.

Ensure that no obstacles are in the direct path or within the defined zone of the two sites.

Consider whether any RF interference is present.
