Troll Introduces Diversity Receiver and Remote Controller for Diversity Antenna Sites

Central receiver models also available

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.

Six Input Diversity Antenna with Embedded Diversity Receiver

Tactical receive site case with Ethernet, WiFi, 3G, 4G, LTE distribution

  • Six panel diversity antenna with embedded diversity receiver and Ethernet decoder
  • Video distribution via the cloud, WiFi or cellular
  • AES 128 or AES 256 encryption
  • MPEG 2 (4:2:2) and H.264 (4:2:2) decoding
  • Up to 15dBi gain
  • Multi-band 1.5GHz to 7GHz
  • Internal block down converters and filters
  • DVR available

The A6 diversity ground antennas are designed to provide high-gain 360° diversity signal reception using six independent sectors with up to 15dBi of gain in each sector. Integrated into the design are high-performance down-converters, and a six-channel diversity receiver. Power for the system is provided over Ethernet to further simplify installation. The A6 antenna system decodes up to six channels of video and incorporates maximal ratio combining and packet switching to ensure robust signal reception.

Local video monitoring, transmission control and POE (Power over Ethernet) is provided by Troll’s TacCase. While live video is processed and bandwidth optimized for real-time distribution via Ethernet, local WiFi, the cloud and cellular infrastructure 3G, 4G, LTE.

Troll’s TacCase is a mobile data terminal designed to receive live air-to-ground video and sensor data in tactical environments.
Easy to deploy, TacCase provides power over Ethernet (POE) to Troll’s tripod mounted six-channel diversity antenna/receiver system. Together they link stabilized video taken from an aircraft with tactical operations on the ground. TacCase provides external HDMI and composite video outputs as well as an integrated touchscreen display for local monitoring and control of antennas, receivers, encoding, decoding and encryption.

TacCase also records and transmits video in real-time over Ethernet, WiFi and cellular 3G, 4G, LTE. Encoding of video and data for transmission to these other networks is automatically bandwidth optimized based on the data rate available. This prevents TacCase from overloading the network during critical operations. TacCase is ideal for airborne law enforcement, military ISR and commercial broadcasters trying to manage and respond to security situations and news gathering opportunities as they unfold on the ground.

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 and GPS telemetry 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 extreme distances, even if GPS data is interrupted.

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.
