|Jampro Antenna / RF Systems of Sacramento, California has announced the shipment of the company's RCHA-323-10HD FM High Power Combiner to the Mass Communications Organization of Thailand (MCOT) to support the country’s inaugural HD radio transmission.
Recently granted a special government license to broadcast HD radio, MCOT will use Jampro's combiner to transmit HD programming to the greater Bangkok public transportation systems. The RCHA-323-10HD, designed for transmitter power levels of 35 plus kW analog, simultaneously sends out a hybrid 10 kW high definition digital signal over the same antenna. The Jampro injector uses In-Band On-Carrier (IBOC) technology to broadcast a digital signal on the same channel, at the same time, as an FM analogue signal.
MCOT, headquartered in Bangkok, is owned and operated by MCOT Public Company Limited, a mass communications company comprised of MCOT Radio Network stations, a TV business (Modernine TV), a news service (Thai News Agency) and joint operations with private parties. MCOT's 62 AM and FM stations broadcast 24 hours a day and reach a nationwide audience with music and news.
The RCHA-323-10HD works with most Jampro antenna models and with other antenna brands that have sufficient bandwidth and symmetrical band pass. This combiner has high levels of isolation, and inputs for analog and digital FM transmitters. The self-cooling features of the unit allow safe combining without the need for AC Powered cooling fans. Jampro can provide the RCHA-323-10HD for use with a station's coax and reject load, or as a system with these components included.
A lower power version, the RCHA-222-10HD is also available.
