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.
