Our ZVCF-136174 is an expandable VHF transmitter combiner cavity filter engineered for high-performance multi-channel radio networks operating across the 136-174 MHz VHF band. Designed for single-channel tuning and rated to 200 Watts, this VHF high band cavity filter enables multiple transmitters to share a common antenna system while maintaining excellent isolation and minimising intermodulation and adjacent channel interference.
Utilising a precision-tuned single cavity design with an integrated T-junction and isolator, the ZVCF-136174 delivers low insertion loss, high transmitter isolation, and dependable RF performance in demanding communications environments. Its expandable architecture allows additional cavities to be added as network requirements grow, providing a scalable solution for evolving radio infrastructure without requiring complete system replacement.

Utilising a precision-tuned single cavity design with an integrated T-junction and isolator, the ZVCF-136174 delivers low insertion loss, high transmitter isolation, and dependable RF performance in demanding communications environments. Its expandable architecture allows additional cavities to be added as network requirements grow, providing a scalable solution for evolving radio infrastructure without requiring complete system replacement.
The filter is ideally suited to Land Mobile Radio (LMR), emergency services, government communications, utilities, transport networks, defence communications, and critical infrastructure where reliable multi-channel operation is essential. By reducing unwanted transmitter interaction and maintaining signal integrity, the ZVCF-136174 helps maximise system performance and spectrum efficiency.
Fitted with N-type female connectors, the unit integrates easily into professional RF installations and can be configured as part of a rack-mounted or site-based communications system. The robust cavity construction ensures long-term stability and repeatable performance, even in continuous-duty and high-demand operating environments.
Each unit is factory tuned (can be field tuned as well) to a specified operating channel within the 136-174 MHz range, ensuring optimum performance for the intended application while retaining the flexibility to expand into larger combiner systems as network capacity requirements increase.
Combining low insertion loss, integrated transmitter protection, scalable expansion capability, and professional-grade RF performance, the ZVCF-136174 from ZCG Scalar is an ideal solution for organisations seeking reliable and future-ready VHF transmitter combining infrastructure.
