The new Maxiva UAXT & VAXT Ultra-Compact family of UHF solid-state Transmitters / Transposers (Translators) and on-channel Gap Fillers expands upon the proven foundation of GatesAir low-power systems and PowerSmart® high-efficiency technology.  It provides today's digital broadcaster with a suite of compatible products to accommodate any coverage application, along with unmatched performance, reliability and quality.


The Maxiva Ultra-Compact family further extends the capabilities of the Maxiva series, providing a single family of transmission products capable of satisfying any coverage architecture.  The Maxiva Ultra-Compact provides pre-filter power levels up to 1,000W, in exceptionally compact and space-saving 1RU, 2RU and 3RU packages.


Designed for both analogue and digital broadcasting, the Maxiva UAXT/VAXT Ultra-Compact is a platform available in Transmitter, Transposer or SFN Gap Filler configurations for DVB-T, DVB-T2, ATSC, ISDB-Tb, DAB/DAB+ and NTSC/PAL analogue networks. The Maxiva Ultra-Compact Series provides an ideal solution for extending market coverage and filling in coverage gaps in challenging situations, including busy urban areas that require greater building penetration.


The Maxiva UAXT & VAXT Ultra Compact family of Transposers and on-channel Gap Fillers provide efficient and reliable re-broadcast of the received signal in a space saving, reliable and robust package. The Gap Filler configuration adds a powerful echo cancellation feature to deliver exceptional on-channel performance.
