Installing an RF Antenna
WARNING!
Radiation hazard – risk of Radio Frequency (RF) exposure. This base station is compliant with the
requirements set forth in CFR 47, section 1.1307, addressing Radio Frequency (RF) exposure from
radio frequency base stations, as defined in
[http://transition.fcc.gov/Bureaus/
Engineering_Technology/Documents/bulletins/oet65/oet65.pdf]. The emitted radiation should be
as little as possible. To achieve minimum RF exposure, install the base station when it is configured
not to transmit and set it to operational mode remotely, rather than having a technician enable
transmission on-site. For maintenance of the base station, or other operations which require RF
exposure, the exposure should be minimized in time and according to the regulations set by the FCC or
the regulations relevant to the country of installation.
IMPORTANT!
The antenna installation must be as per Article 810 of the NEC. Of particular note is the requirement
that the grounding conductor not be less than 10 AWG (Cu). The scheme should be either:
• in accordance with UL 96 and 96A Lightning Protection Components and Installation Requirements
for Lightning Protection Systems
• tested in accordance with UL 50 and UL 497
IMPORTANT!
A Radio Frequency (RF) site survey is recommended prior to any installation to help determine the best
location for the antenna(s). For assistance, contact a Siemens Sales representative.
To install an RF antenna, do the following:
1. Mount the antenna to a pole or wall in an area that provides good signal coverage and is away from any
signal noise emanating from other communications equipment. Make sure 55% of the sky at minimum is
visible to the antenna.
2. Using one of the supplied CAT-5 cables, connect the antenna to the supplied lightning protector.

• For the primary antenna, connect to the
ANT1
port
• For the secondary antenna, connect to the
ANT2
port
Make sure the cable connector is torqued to 1.35 N·m (11.9 lbf-in) at the base station end.
