The ZVBF-136AB-3 is a three-cavity VHF Airband band-pass filter engineered for high-performance RF filtering across the 118-136 MHz aviation communications band. Factory tuned to a specified 200 kHz operating channel and rated to 250 Watts, it provides exceptional receiver protection, out-of-band signal rejection, and improved system selectivity for critical aviation communications.
Utilising a precision three-cavity design, the ZVBF-136AB-3 delivers superior attenuation of unwanted signals while maintaining low insertion loss across the required operating frequency. This significantly improves receiver isolation, reducing desensitisation and interference from adjacent transmitters operating within busy airport and aviation environments.

This significantly improves receiver isolation, reducing desensitisation and interference from adjacent transmitters operating within busy airport and aviation environments.
Designed for professional Airband communications systems, the filter is ideally suited to civil and military airports, air traffic control facilities, aviation ground stations, aerodrome radio networks, and other VHF infrastructure where reliable receiver performance and frequency selectivity are essential.
Manufactured in Australia by ZCG Scalar, each filter is individually tuned to the customer’s nominated operating frequency, ensuring optimum RF performance while allowing customisation to suit new installations or upgrades to existing communications networks. The anodised aluminium construction provides excellent durability and long-term stability in demanding operating environments.
Supplied with N-type female connectors and coaxial joiners, the ZVBF-136AB-3 integrates easily into professional RF installations and can be rack mounted or incorporated into larger filter and multicoupling systems.
Combining high-Q cavity filtering, excellent receiver isolation, low insertion loss, and Australian manufacturing, the ZVBF-136AB-3 from ZCG Scalar is a professional-grade solution for Airband VHF communications where reliable performance and interference mitigation are critical.
