Shown for the first time to commercial broadcasters at NAB, Troll’s DMR series receivers combines 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, 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 preview, control and monitoring of antennas, transmission, test and signal diagnostics. In addition, video can be viewed locally via HDMI, Ethernet or composite.

DMR6000 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 Maximum-Ratio Combining and packet switching to “knit together” signals from different antenna panels to provide cohesive 360°coverage.

The DMR6000 also provides remote control of the entire receive site. It incorporates the latest networking technology, with extensive packet-level advances in diagnostic and test capability. A Linux operating system delivers remarkable performance while providing an Ethernet compatible platform for delivering encrypted HD video and data over IP.

Directional Diversity Tracking Antennas Patented By Troll Systems

August, 14, 2014- Valencia CA – Troll Systems, Corp is awarded a US patent #8,816,933 B2 for Directional Diversity ground antennas.

The first of its kind, Troll’s A600 ground-based antenna system revolutionized microwave communications with the introduction of Directional Diversity RF asset tracking with high-gain directional transmit and receive systems.  Used primarily to extend range, automate operation and improve accuracy, Troll’s air-to-ground transmission systems use diversity antenna arrays rather than GPS aircraft or satellite data to accurately track air, land and sea vehicles without operator intervention.  This automated process, enables Troll’s A600 and other Troll antennas to provide automated signal tracking and Ethernet processing over an extreme distances, using a plurality of antennas to ensure high-performance and accuracy.  

These air-to-ground microwave transmission systems ensure long-range, robust transmission systems that far surpass industry standards for design and functionality.  Extremely accurate and efficient, Troll’s Directional Diversity systems are designed to take maximum advantage of diversity antennas arrays by enabling RF transmission energy to track aircraft location, altitude and heading while allowing the high-gain antenna on the ground to peek on the center of a moving signal.  

Troll Wins Environmental Leadership Award

In 2011, Troll Systems was presented an Environmentally Conscious Leadership Award by the San Fernando Valley Business Journal. Throughout its history, Troll Systems has put environmental initiatives to work.  During building renovations in 2007, Troll implemented many environmentally-friendly changes.  Lighting for the facility is nearly all-natural and is provided by 35 skylights and 41 Solatube™ reflectors. The manufacturing floor, warehouse, engineering lab, and second-floor offices, all utilize natural light and rarely require artificial illumination.  A highly-reflective roof coating and insulation drastically cut heating and air conditioning costs, while a reverse osmosis drinking water system has eliminated the need for disposable plastic water bottles.  A hybrid car was also purchased for local deliveries and travel.

Our manufacturing processes are RoHS compliant.  Known as the "lead-free" directive, Troll voluntarily complies with RoHS. Troll recycles aluminum cans, batteries, ink cartridges, paper and glass throughout its facility. And, employee work schedules have been transitioned to a 9/80 cycle, reducing the energy employees spend commuting to and from work by 10%. 

Troll Systems' A600 Directional Diversity Antenna System Wins Two Engineering Design Awards at NAB 2008

Multi-Frequency, Multi-Channel DVB-T Tracking Antenna Takes Two First Price Awards

The first in a series of Next Generation News Gathering products, Troll Systems’ XNG receive system is a fully self-contained receive site.

The package includes:

  • Six channel DVB-T diversity receiver
  • Unique steerable high-gain directional antenna
  • Five reconfigurable diversity panel medium gain antennas
  • Fully automatic signal tracking with signal tracking software
  • Self-contained form-factor that can be controlled from any remote location

The system is easy to install (only one cable is required from the controller to the antenna), and even easier to operate. Once the receive channel has been set, the A600 manages the link between the RF source and the receiver. When one of the sector antennas detects a signal, the steerable high-gain antenna is automatically peaked and moved to improve signal strength, continuously optimizing its "point-to" position during signal transmission. It is this ability to track “signal integrity” that enables the A600 to outperform all competitive receive site solutions.

Automating the operation of your receive site furthers cost savings by eliminating the need for microwave experts to set-up and operate these antennas.
