ANTENNA INSTALLATION

Mobile Antennas

Recommended mobile antenna installations are limited to metal body vehicles at the centre of the roof and centre

of the trunk deck locations.

The antenna installation must additionally be in accordance with:

a) The requirements of the antenna manufacturer/supplier

b) Instructions in the Radio Installation Manual

Fixed Site Antennas

Mobile radio equipment is sometimes installed at a fixed location and operated as a control station or as a fixed

unit. In such cases the antenna installation must comply with the following requirements in order to assure

optimal performance and make sure human exposure to radio frequency electromagnetic energy is within the

guidelines set forth in the above standards:

The antenna must be mounted outside the building

Mount the antenna on a tower if at all possible

If the antenna is to be mounted on a building then it must be mounted on the roof.

As with all fixed site antenna installations, it is the responsibility of the licensee to manage the site in accordance

with applicable regulatory requirements and may require additional compliance actions such as site survey

measurements, signage, and site access restrictions in order to insure that exposure limits are not exceeded.
