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.

BOOSTER MODULE SETUP
2 digits LED display with booster gain indication [dB].
Brightness can be adjusted through the user menu.
Signaling LED, multicolor:
white : when turning-on indicates the booster start up
yellow : booster bypassed, antenna becomes passive
green : active booster with gain between 1 ÷ 8 dB
blue : active booster with gain between 9 ÷ Max Gain
red : fast blinking, powering insufficient (lower than ≈9,5Vdc)
+ / - , adjusting buttons
MENU/SAVE, selection button allows to edit the following parameters (after 5 second
gain indication is restored by default).
BOOSTER GAIN SETUP , from normal indication:
Push MENU/SAVE to enter gain edit mode,
Then edit the gain with + / - ,
Push again MENU/SAVE for confirm or wait 5 sec to return without saving.
It is possible to setup the gain between 1 ÷ 15/16 dB in steps of 1dB. Decreasing
gain to the lowest value, “bP” is displayed: booster is bypassed and antenna
operates in a passive way. Confirm the new setup value within 5 sec by pressing
one more time on the MENU/SAVE button. Without any confirmation within 5 sec.
the modification is cancelled.
DISPLAY BRIGHTNESS (first digit “d”, second digit value from 0 to 8)
Push twice MENU/SAVE to enter brightness edit mode,
Then setup your desired brightness with + / - ,
Push again MENU/SAVE for confirm or wait 5 sec to return without saving.
PASS THROUGH SETUP
Push 3 times MENU/SAVE to enter brightness edit mode,
Then setup your pass through with + / - :
“b0”is no 12V pass through
“b1” is 12V pass through Enabled.
Push again MENU/SAVE for confirm or wait 5 sec to return without saving.
ON/ALARM BLINK IN RED TO INDICATE LOW VOLTAGE
ERROR FEEDING VOLTAGE UNDER 10V:
-CHECK YOUR FEEDING CABLE
-CHECK YOUR ANTENNA (TAKE OUT THE INPUT CONNECTOR AND CHECK)
-CHECK YOUR FEEDING DEVICE (SPLITTER, RECEIVER) TO BE ABLE TO
SUPPLY ENOUGH CURRENT (100mV @ 12V)
