With the newly introduced AGC (Automatic Gain Control) present in all FCC certified consumer boosters, outside signal can now be considered “too good,” causing the amplifier to shut down. Amplifiers work best with an outside signal between -90dB and -65dB, but if the outside signal is better than -65dB, you can use one or more RF Attenuators to reduce the amount of decibels entering the booster and prevent a possible AGC overload. 5db, 10db, and 20db attenuators are available, and you can group these attenuators together to attenuate as many decibels as is necessary.
The attenuator has N/Female and N/Male connectors and connects directly to the "outside antenna" side of the amplifier.
