BAA
BROADBAND ANTENNA AMPLIFIER
BAA is wideband antenna booster especially designed to allow using long cables with
broadband wireless receiver system working in 470-870 MHz (TV ch 21/70) thanks to a
very high OIP3 of 40 dBm.
Operation
The BAA is powered by the receiver system through the coaxial cable attached to its output
connector, and accordingly the receiver system must have the antenna feeding function.
BEWARE:
BAA need 100mA @ 12V to operate and it can feed a further antenna booster up
to 100mA @ 12V.
BAA housing is in ruggedized aluminum, with waterproof sealing (suitable for outdoor
installations):
2 holes for wall-installation (M4 screw type)
Radiofrequency connectors are BNC-Female type:
Input connector
, to antenna. it is possible to power up a remote booster (up to
100mA). When input power is active, “INPUT DC BIAS” led is on. If there is fault on
remote booster (i.e. a short circuit) then a L appear on left digit of gain display .
Output connector
, to receiver system. BAA is powered thru this connector (100mA
+ 100mA if input powering), if there is a fault (low power) a L appear on right
digit of gain display .
GAIN SETUP
BAA gain can be setup in 16 steps (0÷15 dB typical) using
+/-
buttons.
A multi-colored (RGB) led will indicate the gain level band and also main alarms.
