A robust low-power problem-solver for broadcasters from GatesAir

GatesAir has introduced a new weatherproof transmitter series built for challenging coverage areas and install points. The Maxiva PMTX-1 integrates a low-power UHF TV transmitter or transposer to support an array of use cases, from filling coverage gaps to delivering focused broadcast content as a spot transmitter. 

The Maxiva PMTX-1 is packed within a weatherproof enclosure, making the transmitter impervious to weather elements, with adaptability to any climate or outdoor environments. More particularly, this sealed metal housing is able to remove heat from the internal circulatory system, and perform in extreme temperatures and humidity levels.  

The avoidance of moving parts is coupled with the PMTX-1’s installation versatility. Flexible mounting options support a variety of scenarios to optimise coverage, including a pole-mount configuration for hilltop positions and remote locations with no building or tower. The PMTX-1 also mounts securely to building structures and traditional broadcast towers, providing broadcasters and network operators with more outdoor installation scenarios. 

The PMTX-1 supports single-frequency network (SFN) configurations for DVB-T2, ISDB-Tb, and other digital TV networks, where multiple transmitters operate on the same frequency to maximise signal penetration. 

The PMTX-1 is also available for analogue TV networks, with a field-upgradeable path to DTV. Broadcasters can add optional inputs to support DVB-S/S2 receivers and IP transport streams, and accept broadcast content and data from alternate sources. 

The optional RF receiver input of the PMTX-1 supports flexible options for translator and transposer configurations, and will regenerate content for targeted coverage areas at low power levels. Built-in GatesAir RTAC technology for real-time adaptive pre-correction ensures a fully compliant solution for any broadcast standard, and keeps the broadcast signal within its required spectral limits. 

Ted Lantz, Vice-President, Product Line Management, GatesAir, said, “Transmission networks continue to evolve and change, requiring flexible solutions that are adaptable to emerging network models and configurations.

“The PMTX-1 is a problem-solver for any broadcaster or network operator transitioning to an SFN, filling in coverage gaps, or requiring a low-power solution for a specific market or region.”

Indeed, the all-weather flexible PMTX-1 can resolve the varying needs of the different stages of broadcast development in the diverse nations in the Asia-Pacific region.
