Options

Low gain, 50 dB typical

High Output power, P1 dB = +20 dBm minimum

Excellent guaranteed gain stability due to built-in temperature compensation circuit (test data provided)

Universal input AC power supply

Redundant LNA systems minimize system downtime due to LNA failure by providing a spare LNA and an automatic means of switching to the spare upon failure of a primary LNA. A 1:1 system provides one spare LNA for one primary LNA. A 1:2 system provides a spare LNA for either of two primary LNAs. The systems consist of an outdoor plate assembly which mounts at the antenna hub, an indoor control panel and interconnecting control cable.
