Maxiva™ UAXT Multi-Compact / VAXT Multi-Compact

UHF/VHF Low Power Multi-Transmitter / Transposer / Gap Filler

OVERVIEW

The new Maxiva™ UAXT/VAXT Multi-Compact family of UHF & VHF 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.

Today’s broadcasters and network operators are continually searching for more efficient and economical approaches for providing reliable over-the-air transmission. When several DTV channels can be consolidated into one common transmission site, the cost and space requirements for individual equipment per channel can often be very significant. The innovative Multi-Compact architecture allows the possibility of many configurations, with up to 8 independent low power transmitters, transposers or gap fillers, to be configured into a single space-saving chassis. The Maxiva Multi-Compact provides pre-filter power levels up to 15W per module, in a compact and convenient 4RU 19” rack mount package.

Designed for digital or analog broadcasting, the Maxiva Multi-Compact is a platform available in Transmitter, Transposer or SFN Gap Filler configurations for DVB-T/H, DVB-T2, ATSC, ATSC-MDTV, ISDB-Tb and analog networks. The Maxiva Multi-Compact can be configured for up to 8 independent systems, or as N+1, N+2 or N+1/M+1 configurations.

Instead of investing into several separate transmitter units, as well as complex and costly redundancy management systems, broadcasters or network operators can now simply invest into a single 4RU Multi-Compact transmitter and operate up to 7 channels with +1 redundancy in a single compact unit.
