DOWNLINK

UPLINK

1 dB 2 dB 4 dB 8 dB 16 dB

Additive combination effects:

• Switch 1 (1 dB) + Switch 2 (2 dB) = 3 dB attenuation

• Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) = 7 dB attenuation

• Switch 1 (1 dB) + Switch 2 (2 dB) + Switch 3 (4 dB) + Switch 4 (8 dB) = 15 dB attenuation

•Switch1(1dB)+Switch2(2dB)+Switch3(4dB)+Switch4(8dB)+Switch5(16dB) = 31 dB attenuation. A few

practical attenuation example:

Important Note: Turn ALL uplink attenuation DIP switches to ON and adjust them back one step at a time until uplink connectivity is made

with the Emergency Radio Tower.

• Turning all switches OFF = 0 dB attenuation (booster is at full gain).

• Turning ON switch #1 in a bank = 1 dB attenuation (booster maximum gain is reduced by 1 dB).

• Turning ON switches #1, 3, and 5 in a bank = 1+4+16 dB attenuation = 21 dB attenuation. For example, in an 80 dB booster, the

selected channel is reduced to 59 dB (80 dB ‐21 dB).

• Turning ON switches #1, 1, 4, and 5 in a bank = 1+8+16 dB attenuation = 25 dB attenuation. For example, in an 80 dB booster, the

selected channel is reduced to 55 dB (80 dB‐25 dB).

Note: When all the switches in a bank are turned on, the corresponding

RF link will be shut down. And the maximum attenuation is 25dB for

each link.

When the BDA is powered on, the green Power Light (3) should

illuminate.

• If any of the bands are oscillating, the corresponding band lights (1

and/or 2) will flash red and that band will eventually shut down if

adjustments are not made.

Note: In general, the uplink and downlink DIP switches should be set

identically but this is not always the case.
