DDAMTEK LNA-2000

Broadband amplifier with low noise level and built-in attenuation filter for the GSM band
The preamplifier is powered via the coaxial cable - either with DDAMTEK's PWR-I or via the receiver if it supports the bias tee.

Instructions for use: Antenna is connected to F-connector INPUT
PWR-I or receiver with T-bias is connected to F-connector OUTPUT.

Please note that the preamp works for receive only! Transmitting through the LNA will damage both the LNA and your transmitter.
