To whom it may concern,
I respectfully submit this written request for a special exception from Section 5.1.40 of the Personal wireless service
facilities, collocation, replacement, and removal of transmission equipment ordinance. Specifically, AT&T is requesting
a special exception from provision 2(c) of the Development Requirements of Section 5.1.40 which requires that "no antenna
shall project from the facility, structure or building beyond the minimum required by the mounting equipment, and in no
case shall the closest point on the back of the antenna be more than twelve (12) inches from the facility, structure, or
building; and in no case shall the farthest point of the back of the antenna be more than eighteen (18) inches from the
facility, structure,
or building..."
The proposed installation will mount the antennas 63 inches from the tower and will require that the antennas be located
at 84'.
There are multiple frequency bands licensed to AT&T. The frequency band licensed to AT&T for the First
Responder Network and frequency bands licensed to AT&T for consumers cannot operate from the same antenna.
These frequencies require multi beam panel antennas to operate. To achieve the network objective and optimal
coverage area, it is recommended to install these antennas at the same height with different azimuth. Since the antennas
should be mounted at the same height, optimally they must be more than 12 inches from the tower facility to meet
the required separation distance from the tower and the other antennas.
In summary, it is my professional opinion as the radio frequency design engineer that the proposed RAD height is
the required height necessary in order to provide optimum coverage to meet our requirement of providing excellent
wireless services to your citizens in this area.
