ZCG Scalar ZVCF-136174 VHF expandable transmitter combiner cavity filter

In today’s fast-paced environment, reliable communications are essential for ensuring safety and operational efficiency across diverse sectors. The ZCG Scalar ZVCF-136174 VHF expandable transmitter combiner cavity filter delivers high performance in the 136–174 MHz spectrum and has been engineered for high-power applications up to 250 W. The precision-tuned filter is designed to enable clear communications when it matters most.

The product has the versatility to meet the unique demands of critical communications. With multichannel combining, it can seamlessly integrate multiple RF signals, optimising spectrum utilisation. Its high isolation (noise suppression) minimises interference between channels, while close channel separation enables robust performance even in high-density environments. The unit’s low insertion loss maximises signal strength and system efficiency. It is suitable for fixed (stationary) base-station applications in the emergency services, mining, trucking and transport sectors.

Constructed with a clear chromate-finished aluminium cavity body, conductive internal components and temperature-resistant INVAR tuning internals, the product is built to perform under demanding conditions. PTFE insulators and tri-metal plated N-type female connectors further enhance durability and RF performance. Its broadband design and ease of expansion make it suitable for high-density channel environments and future network upgrades with minimal disruption.
