GatesAir’s Maxiva PMTX-1 Provides Network Operators, Local Broadcasters With Many Low-power Options
GatesAir PMTX transmitter.
Utilizing many of the same attributes as its UHF predecessor, the Maxiva PMTX-1 integrates a low-power transmitter or transposer/translator to support a diverse array of VHF and DAB use cases, from filling coverage gaps to delivering focused broadcast content as a spot transmitter.
Its rugged, telecom-grade enclosure makes the PMTX-1 impervious to weather elements, with adaptability to any climate or outdoor environment thanks to its sealed protective shell. The VHF version covers channels 7 through 13 and is mainly marketed for use in North America and the Asia-Pacific (APAC) region. In mixed spectrum networks, broadcasters can take in a UHF signal and translate it to a VHF output, for example.
The DAB version is viable for countries that have adopted DAB/DAB+ as its digital radio standard in regions outside North America, with especially strong business opportunities in Europe and APAC. In Europe, the PMTX-1 simplifies DAB broadcast service for tunnels, complex terrain that limits coverage, and areas shadowed by buildings and other obstacles.
In addition to pole-mount configurations, the PMTX-1 also mounts securely to building structures and traditional broadcast towers, providing broadcasters and network operators with seemingly endless outdoor installation scenarios. That makes the PMTX-1 ideal for single-frequency network (SFN) configurations where multiple transmitters operate on the same frequency to maximize signal penetration. The PMTX-1 is also available for analog TV networks (100 W), with a field-upgradeable path to DTV (50 W for ATSC, DVB-T, DVB-T2 and ISDB-Tb).
Field operations are also simplified through the Maxiva PMTX-1’s clever one-piece design, which removes all moving parts and air filters to eliminate most maintenance requirements. The sealed metal housing efficiently removes heat from the internal circuitry and performs well in extreme temperatures and humidity levels. This innovative and effective approach to heat management maximizes efficiency and keeps utility costs low.
The PMTX-1 VHF and DAB version is almost analogous to the UHF version in design characteristics and componentry, with the mask filter and power amplifier as the only exceptions. 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. Broadcasters can add optional inputs to support DVB-S/S2 receivers and IP transport streams, and accept broadcast content and data from alternate sources.
