VHF Receiver

The MT-4Z VHF Receiver

Capable of working in the same challenging terrains, the MT-4Z VHF receiver matches the MT-4E series’ exceptionally low-current draw, making it ideal for use in extreme conditions. This new iteration in the MT-4 series continues to push the limits of what Land Mobile Radio (LMR) communications infrastructure can do.

As the successor to the MT-4E Series, the cornerstone of Zetron’s LMR solutions portfolio, the MT-4Z VHF receiver offers the same reliability and capability as its predecessor, only now in a fully software defined radio module. 

The picture of versatility, the MT-4Z is ideal for both fixed and tactical applications. Flexibility is essential, so the MT-4Z is compatible with all MT-4E configurations, including repeaters, base stations, crossband, paging, voting and simulcast, and more. 

RSS Configurator Tool

As Zetron’s first fully software defined receiver, the MT-4Z offers the ability to adjust itself across the entire VHF band (136-174MHz). Thanks to the RSS configurator tool, this can all be done without having to physically access the pre-selector. The receiver is easily adjusted without any tools or special training requirements. Simply connect a laptop or other Windows terminal to the USB interface on the radio and run the RSS configurator tool.

Note: The MT-4Z requires the RSS tool version or newer

MT-4Z VHF Receiver Core Features

Like the MT-4E series, The MT-4Z draws, on average, less than 115mA of current. It can be easily swapped in to operate in the same DC-powered sites and remote areas relying on solar power as the MT-4E.

The enduring nature of the MT-4Z can be partially attributed to its ability to operate in everything from freezing to blistering conditions. You can count on it to remain operational in a wide range of temperatures. 
The software-tuned filter offers quick and tool-less receiver adjustment, more efficient than manually adjusting the pre-selector. 

The MT-4Z VHF receiver has an improved noise figure, hum-and-noise ratio, and adjacent channel & intermodulation rejection compared to the MT-4E; this means enhanced coverage, better voice quality, and fewer errors for both analog and P25 calls. 

Through an optional MT-4Z helical filter module that can be integrated into the receiver, the user can switch between the new software tuned filter and the classic MT-4E style helical filter.
Compatibility with MT-4E configurations like repeaters, base stations, crossband, paging, voting and simulcast, and the ability to swap between helical filter modules through the RSS configurator tool, means the MT-4Z is capable of meeting even the most unique needs.
The MT-4Z VHF Receiver has been designed with full compliance to industry standards, such as APCO P25 and various TIA published standards, allowing for interoperability with other compliant third-party products.
