Diversity Receiver with Embedded Remote Site Antenna Controller

IP-Based Remote Control for Multi-Band Diversity Receive Sites and Distributed Receive Systems

Troll’s DMR series of products combine a multi-channel microwave receiver with a remote site diversity antenna controller. The combination provides a two (2) to eight (8) channel diversity receiver for remote Electronic News Gathering (ENG) or law enforcement antenna sites. The DMR processor performs video decryption, encryption, audio/video decoding for local monitoring and secure IP transport to remote control centers.

The DMR’s front panel touchscreen enables live video and audio preview, control and monitoring of antennas, carrier levels, test and signal diagnostics. In addition, video can be viewed locally via HDMI, Ethernet or composite.

DMR8000 receivers can be daisy chained together to receive multiple RF signal sources on different channels simultaneously. This passive “loop through” feature makes it possible to support multiple aircraft and ground vehicles with a single diversity antenna. DMR receivers incorporate Maximal Ratio Combining and packet switching to “knit together” signals from different antenna panels to provide cohesive 360°coverage. The DMR8000 interfaces directly to all Troll Systems antennas, including the A1 and A6 family of diversity panel antennas.

The DMR system provides remote control of the entire receive site. The modern design incorporates the latest networking technology, with extensive packet-level advances in diagnostic and test. A Linux operating system delivers remarkable performance while providing an Ethernet compatible platform to route encrypted HD video and data to control centers and cloud-based infrastructure.
