ABF-128 VHF Airband Filter

The ABF128 is a high-performance bandpass filter designed for the VHF airband. It can be used not only with aviation radio receivers but also with wideband receivers, and it can be easily installed on both our receivers and commercially available wideband receivers.

By installing this high-performance filter between the receiver and the antenna, it enhances the front-end characteristics of the receiver within the airband frequency range, reducing interference from strong signals such as TV broadcasts. This prevents signal intrusion and sensitivity suppression in the airband.

Designed using CAD and circuit simulation software, the ABF128 features a compact and smart design that is also suitable for portable use. It provides an attenuation of 40 dBm for broadcast frequencies below 90 MHz and television broadcast frequencies above 172 MHz.

The connector type is BNC.
