UHF Antenna Line Coupler Suits APM3852 Series

The APM provides comprehensive RF performance measurement, monitoring and alarming of Tx forward and reflected powers, combiner losses, and Rx RSSI levels on a truly channelized basis – for up to 80 channels.

SKU: SP3855-4440-DFF1RU Category:

It also provides unique measurement, monitoring and alarming of the Rx subsystem (Rx Antenna/TTA/RMC), Tx-to-Rx Antenna Isolation(s), and Tx-to-Rx Carrier Rejection performance. The Antenna Line Coupler(s) is inserted after the Tx combiner on the antenna feeder cable. All frequencies, channel bandwidths and level thresholds are software definable. A DB15 rear mounted connector provides alarm relay outputs that can be hardwired into most alarm reporting facilities. Configuration, diagnostics and communication management are facilitated through the use of an on-board webserver GUI. The APM is available in four different bands covering VHF, UHF, 7/800MHz and 8/900MHz frequency ranges.

  • True channelized power and VSWR metering for multi-channel, digital and analog systems.
  • Non-intrusive measurement of Tx forward and reflected power and Rx RSSI levels for up to 80 channels – and System Rx Subsystem, Antenna Isolation(s) and Tx-to-Rx Carrier Rejection performance
