VHF Antenna Line Coupler Suits APM1317 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: SP1318-2440-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
  • Accommodates up to four (or more) separate transmitter combiners
  • Integral webserver GUI for Measurement value, History Chart and Alarm Status viewing, and unit configuration
  • Supplied with one Antenna Line Coupler, additional couplers ordered separately.
  • Supported by Genesis GenWatch® and C² Systems SitePortal® software packages
  • Supports SNMP GET and Traps, SMTP (Email), and Relay outputs for alarm reporting
  • Optional Site Alarm Module (SAM) and Receive Systems Module (RSM) for enhanced functionality
