Page 1 ENG Truck Systems Digital and Analog

Microwave Equipment for ENG truck systems must be rugged, compact, reliable, easy to operate, and offer the performance and agility required to deliver the story. Truck systems built by BMS are designed expressly for the demanding environment of field ENG use.

Truck system packages purchased from BMS include all mating connectors for your installation or may be supplied directly to your truck system integrator.

BMS now offers the most powerful digital ENG truck system comprised of a BMS Truck-Coder II and BPA-10CC 10 Watt power amplifier.

The Truck-Coder II is a compact rack mountable device dedicated to set up wireless digital transmission of audio, video, and data signals. This easy to operate system includes 4:2:0/4:2:2 MPEG-2 encoding, COFDM digital modulation, and RF amplification. The Truck-Coder II features pre-defined or user selected operating modes designed to achieve the best trade off between robust transmission, video quality, and end to end delay. This system is ideal for fixed, portable, and mobile applications for non-line-of-sight operation.

The backbone of the analog ENG truck system is the high power BMT75 Series Transmitter. It offers a ver-satile transmit package for all vehicle applications while being cost and space efficient. This transmit-ter is mounted at the antenna to minimize RF loss. Inside the truck, BMS’ TCP-100 control panel offers a compact, (1 RU), intuitive interface. This control panel can control dual transmitters mounted at the antenna providing redundant systems or simultane-ous dual band operation.

Video, audio, DC power, and pedestal controls are fed through at 0.5” maximum diameter cable bundle from the TCP-100 to the mast-mounted transmitter. This leaves room for additional cables within the Nycoil™ sheath to control operational mast-mounted equipment such as POV camera, off-air antenna, etc. using a .75” to 1.25” diameter Nycoil™.

Transmitters operate from 11-32 VDC and require 2.5-7.5 amperes, (voltage dependent), per transmitter. BMS recommends operation at 24-28 VDC to avoid voltage dropping below 12 VD at the top of the mast. A BVC-12-28-5A Voltage Converter can be supplied for 12 VDC operation, or a TPS100-28-6A rack mount power supply for AC operation.

BMS offers a family of antennas to suit your requirements which are available in single polarity, dual polarity, 4-polarity, and dual band operation. The most popular are the BMA-20/30 Offset Feed Antenna and the BMA-2/4 Truncated Parabolic Antenna.

In choosing the right antenna, characteristics must be considered regarding gain and beamwidth versus size/weight and aerody-namic loading. Higher gain is desirable to maximize distance. However, with higher gain comes larger size. Beamwidth is impor-tant in determining required aiming accuracy. Beamwidths narrow with larger size antennas and higher frequencies. Low-profile stowage for transport must also be considered. All BMS antenna mounts allow stowage at 90 degrees.

Options include SMPTE color bar generator with 16 character ID, dual audio tone generators and a video detector that will re-motely turn the transmitter on when video is present.
