The PMTX-1 is also available for analogue TV networks (100 W), with a field-upgradeable path to DTV.
GatesAir, a wireless content delivery solutions provider, has introduced Maxiva PMTX-1, a self-contained, modular outdoor transmitter series that integrates a low-power UHF TV transmitter or transposer/translator for use in a variety of applications, including filling coverages gaps and delivering focused broadcast content as a spot transmitter.
The Maxiva PMTX-1 is housed in a rugged, telecom-grade enclosure, making it impervious to weather. Due to its sealed protective shell, the transmitter can be adapted to any climate or outdoor environment.
The one-piece design from the company’s Europe-based engineering team removes all moving parts and air filters, thereby removing most maintenance requirements. Its metal housing efficiently removes heat from the transmitter’s internal circuitry and helps to ensure it performs well in extreme temperatures and humidity.
This heat management approach maximises efficiency and reduces utility costs. The PMTX-1 also uses an integral mask filter to reduce external components and make maintenance nearly non-existent.
A variety of mounting scenarios are supported, including one of the first pole-mount configurations in the industry, which is useful for hilltops and remote locations where there is not building or tower. The PMTX-1 also mounts securely to building structures and traditional broadcast towers, providing broadcasters and network operators with endless outdoor installation scenarios. This makes the transmitter well-suited for 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 (100 W), with a field-upgradeable path to DTV (50 W for ATSC 1.0, DVB-T, DVB-T2 and ISDB-Tb). Broadcasters can add optional inputs to support DVB-S/S2 receivers, IP transport streams and accept broadcast content and data from alternate sources. The PMTX-1’s optional RF receiver input supports flexible options for translator and transposer configurations and will reliably regenerate content for very 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.
Speaking about the transmitter, Ted Lantz, Vice President, Product Line Management, 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.”
GatesAir plans to expand the groundbreaking PMTX-1 series, with VHF TV and DAB Radio capabilities expected later this year. The PMTX-1 Series will also be upgraded to support other digital TV modulations, including ATSC 3.0 and DTMB, in future product generations.
