The ZCO174NF is a 2-way VHF hybrid combiner engineered for combining two transmit or receive paths into a single antenna system across the 136-174 MHz frequency range. Rated for 200 W total power handling (2 × 100 W inputs), it provides a compact and reliable solution for professional VHF communications where reducing antenna infrastructure and maintaining RF performance are essential.
Designed to deliver port isolation of 23dB (minimum), 3.7dB (maximum) insertion loss, and accurate impedance matching, the ZCO174NF enables two VHF high band radio systems to share a common antenna while minimising interaction between connected equipment. This improves overall system efficiency, simplifies site installations, and reduces the need for additional antennas and mounting structures.
