GatesAir Debuts Efficient, Compact Gap-Fillers

GatesAir expands Maxiva TV transmitter brand with two new gap-filler solutions.

At NAB 2015, GatesAir unveiled two new low-power TV platforms that address two different needs.

Designed for digital broadcasting, the Maxiva Ultra-Compact is a platform available in Transposer or SFN Gap Filler configurations for DVB-T/H, DVB-T2, ATSC, ATSC-MDTV, ISDB-Tb, CTTB and DAB/DAB+/DMB networks. The Maxiva Ultra-Compact Series provides an ideal solution for extending market coverage and filling in coverage gaps in challenging situations. Power levels of 30, 50, 80 and 130 watts are available.

The GatesAir Maxiva Multi-Compact series is a high-density, 4RU, UHF and VHF transmission system available in several configurations, including N+1, N+2, or N+1+M+1 redundancy. The Multi-Compact series provides a single chassis to house up to eight separate 15 Watt transmitters, translators or on-channel gap fillers, and provides the most compact design available, along with multiple redundancy options and configurations.

The Maxiva Ultra-Compact and the Multi-Compact share performance and efficiency attributes with GatesAir’s market-leading medium-to-high power Maxiva transmitters. All provide exceptional over-the-air quality with a green, cost-reducing architecture that slashes energy consumption, power bills and maintenance requirements. Both systems are fully broadband across UHF and High VHF, ensuring a frequency-agile design that removes any concerns about future spectrum re-pack. The broadband design also greatly reduces spare part holdings for group owners with multiple systems to maintain.

Collectively, GatesAir Maxiva brand provides a full line, single-source family of transmission products to support DTV networks of any size and scale. Maxiva Ultra-Compact and Multi-Compact series’ are available for multiple DTV standards, including DVB-T/T2, ISDB-T/Tb and ATSC, with many input interfaces to ensure complete, interoperable solutions for any DTV network.

On the performance side, cutting-edge echo cancellation and optimized Modulation Error Ratio (MER) performance far outperform competitive solutions, drastically reducing reception problems in difficult reception conditions. The exceptional MER performance is especially important for low power and gap filler performance, eliminating imperfections tied to signal noise and distortion.

Translators can be configured in two distinct ways: A simple, zero IF, direct conversion model; or a re-generative version that provides complete down-conversion to baseband, together with re-modulation to RF with full adaptive correction of the signal. The re-generative version provides the best solution for multi-hop scenarios, preventing progressive signal degradation along the path. The net result is a more robust received broadcast signal for viewers, providing optimum reception over adverse terrain and viewing conditions.
