Auto-tracking high-gain directional antenna

Power, Serial, Ethernet and Control over Fiber

For more than 25 years, Troll Systems has been an indispensable part of the commercial broadcast industry. As a manufacturer of air-to-ground HD video data links, video receivers, controllers and transmission systems, Troll equipment is found in nearly every broadcast news facility in the fifty largest DMA’s in the country.

An aperture efficient offset parabolic design, the AX3000 is made of lightweight carbon fiber and features automated alignment, acquisition and tracking software. Power, Ethernet, RF and Control is provided via fiber up to 2,000 feet. These antennas are available in BAS configurations with Troll’s S8000 antenna controller or DMR8000 two to eight input diversity receiver /controller.

Since 2008, Troll’s NEXT GENERATION NEWS GATHERING (XNG) concept combines high-gain directional tracking with 360° diversity broadcast infrastructure products. Today, redundant video streams from remote site antennas can be monitored and combined at a “packet level” to support numerous transmissions on the same frequency without interruption.

A6 - six-channel, multi-band diversity antenna

The A6 diversity ground antennas were designed to provide high-gain 360° diversity signal reception without the cost and complexity of a dedicated tracking system. Each antenna uses six independent sectors with overlapping reception beam-widths. Integrated into the design are high-performance UHF down-converters with exceptional selectivity characteristics. This conversion to a UHF lowers cost, minimizes cable loss, reduces noise and improves efficiency.

A6 sector antennas can produce up to 15dBi of gain in any one direction and are available in single to tri-band configurations.

  • Six high-gain sector antennas
  • 1.4 to 7.1GHz – single to tri-band
  • Compact – lightweight Internal BDCs and filters as required
  • Simultaneous multi-band options available
  • Permanent and tripod mounting options
  • Up to 15dBi gain
Ultra-Wide Band Diversity Panel Antenna

2.0 GHz – 2.5 GHz Diversity Sector Antenna



COFDM diversity receiver with built-in antenna controller

Network managed UDP streaming and remote control

Troll’s DMR series of products combine a multichannel DVB-T microwave receiver with a remote site diversity antenna controller. The combination provides a two (2) to eight (8) channel diversity reception and video processing for remote Electronic News Gathering (ENG) or law enforcement antenna sites. The DMR processor performs video decryption, encryption, video and audio decoding for local monitoring and secure IP transport to remote control centers.

The DMR’s front panel touchscreen enables live video and audio decoding, remote control, monitoring and signal diagnostics. Receiver stacks can be daisy chained together to separate multiple RF signal sources from different channels simultaneously. This passive “loop through” feature makes it possible to support multiple aircraft and ground vehicles with a single diversity antenna. To enable the smooth transition between each sector, DMR receivers incorporate Maximum-Ratio Combining and packet switching to “knit together” signals from different antenna panels. This ensures redundant streams of video and data are collected for every panel on a packet level.

Master and Remote Controlled Receive Site Infrastructure for Wireless ENG / XNG Contribution Video

NorthAmericaNight1500 1 1

A major manufacturer of microwave communications equipment for the commercial broadcast industry, Troll Systems has been the standard at receive sites since the BAS era. Troll’s air-to-ground video data links, ground receive systems and master controllers are currently used by nearly every local or national news department in the top-fifty U.S. DMA’s

Now legendary, virtually all Troll’s BAS hardware and software infrastructure has been operating reliably and without interruption since 2008.
