The TMAT1921B68-21-43 from CommScope is a Tower Mount Amplifier (TWA) that operates from 555 to 894 MHz and 1695 to 2200 MHz. On the Tx side (downlink), it has an insertion loss of less than 0.45 dB and provides an out-of-band rejection of more than 55 dB while on the Rx side (uplink), it provides a gain of 12 dB with a noise figure of 1 dB. This twin-diplexed antenna is based on the AISG 2.0 protocol (each subunit) and can handle a lightning surge current of 10 kA. It requires a DC supply from 7 to 30 V and consumes 240 mA of current (at 12 V). This antenna is available in a pole/wall-mount enclosure that measures 231.5 x 220.5 x 106 mm with 4.3-10 (female) and 8-pin DIN (female) AISG connectors.
