TV A Crítica Adopts IMT for HD
Brazilian TV station expands wireless microwave gear toolkit
MANAUS, BRAZIL—Integrated Microwave Technologies said
it signed a deal to provide a range of wireless
microwave equipment to Brazilian broadcasting station TV A Crítica, a Rede Record affiliate.
Videodata, a Brazilian systems integrator and
equipment supplier, facilitated the purchase, which included IMT’s RF Central
RMR-X6-II Six-Way Diversity Receiver, Nucomm CPTx-II Compact Video Transmitter,
two RF Central microLite HD Elite Systems, one in the 5.8-GHz unlicensed
and the other in the 2-GHz licensed band, an additional RF Central microLite
MPEG-4 Receiver as well as associated block-down converters and antennas. The
IMT equipment will be used by the station to support broadcast operations in
Manaus, the capital city of the Brazilian state of Amazonas.
A Crítica will use the CPTx-II for
air-to-ground broadcast coverage. It will function as a portable link with a
directional antenna with associated custom mount and it can also be fitted onto
a motorcycle with IMT’s designated mount. The station will also employ it as
part of its helicopter fleet, as the transmitter can be mounted on a standard
ARINC tray, which comes as part of IMT’s motorcycle mount.
