MECHANICAL SPECIFICATIONS:
Size : 18.1 x 16.0 x 9.1 inch
: (460 x 406 x 231 mm) approx.
RF Connectors : N-type Female
Weight : 48 Lbs. (21.7 kg.) approx.
ENVIRONMENTAL CONDITIONS:
The unit is designed for indoor applications:
Operating temperature: - 20°C to + 50°C
Storage temperature: - 50°C to + 90°C
BDA CONNECTIONS
The BDA AC power is accepted through a standard 3-wire male plug (IEC-320) with
phase, neutral and ground leads. The AC power is wired to a high efficiency DC
switching power supply which is CE and UL approved. The power supply runs the
amplifiers and the Power On lamp. The metal enclosure of the BDA is connected to
ground. An optional 9-pin D-Sub connector provides failure alarm output contacts (see
diagram next page) as well as an optional 12 VDC (250mA) auxiliary output.
The RF connections are made via two type “N” female connectors. The RF connector
labeled “BASE” must be connected to the antenna pointing towards the base station.
The RF connection labeled “MOBILE” must be connected to the antenna facing the area
to be covered by the BDA. The RF connections must be made through cables with
characteristic impedance of 50 ohms.
The isolation between the base station antenna and the mobile antenna should be
at least 12 dB higher than the BDA gain. Isolation less than this value can cause
gain ripple across the band. Isolation equal to or less than the BDA gain will give
rise to oscillations which will saturate the amplifiers and possibly cause damage
to the BDA.
RF EXPOSURE WARNING
In order to satisfy the FCC RF exposure requirements, the BDA/antenna installation
must comply with the following:
The outdoor antenna (Yagi type or similar directional antenna) must be installed so as
to provide a minimum separation distance of 0.3 meters (30 cm) between the antenna
and persons within the area. (This assumes a typical antenna with gain of [10.1 dBi,
VSWR ≤ 1.5:1, Zo= 50 ohms, and a cable attenuation of between 1-10 dB).
The indoor antenna (omni directional) must be installed so as to provide a minimum
separation distance of 0.2 meters (20 cm) between the antenna and persons within the
area. (This assumes a typical wide-beam type antenna with gain of 0-2 dBi, VSWR ≤
2:1, Zo= 50 ohms, and a cable attenuation of between 1-10 dB).
