RF EXPOSURE WARNING:
In order to satisfy the FCC RF exposure requirements, you must ensure that
the installation complies with the following:
One antenna is connected via cable that has 3~10 dB attenuation (depends
on the length of the cable) to the CBDA BASE port. This antenna is installed
outdoor and has very sharp beam (Yagi type or similar) pointed to the donor
(BTS). This type of antenna has about 10 dBi gain. Typical specifications:
(model ASPD2996): gain: 8dBd (=10.1dBi), VSWR: better than 1.5:1 ,
Impedance: 50 ohm, F/B ratio: 18 dB, E-plane Beamwidth: 47deg., H-plane
Beamwidth: 58 deg. You must maintain a minimum distance of 0.3m from the
outdoor antenna to people within the area.
The second antenna is connected via cable that has 2~6 dB attenuation
(depends on the length of the cable) to the CBDA MOBILE port. This type of
antenna is omnidirectional (isotropic) with 0 to 2 dBi gain and is installed and
distributes indoor (in buildings, tunnels, basements, park lots, shopping
centers etc.). This antenna is installed usually on the ceiling. Typical
specifications: (Kathrein model No. 741 572): gain: 2dBi, VSWR: better than
2:1 ,Impedance: 50 ohm, Polarization: Vertical. You must maintain a minimum
distance of 0.1m from the indoor antenna to people within the area.
