ADSB Filter Passband and purpose: Transmission range 11.2 GHz; designed to modify ADSB interfaces. The pass filter prevents interference from frequencies outside the pass range, helping to protect ADSB signals. Key benefit: Improves ADSB reception reliability by reducing outofband interference, especially when there is significant interference around 1090 MHz. Compatibility: Intended for ADSB interfaces and receivers operating in the 11.2 GHz band; suitable for standard ADSB setups that use this frequency range. Performance focus: Passband is 11.2 GHz to pass desired ADSB signals while suppressing outofband signals that can cause disturbance. Use scenarios: Groundbased ADSB receiver in environments with strong outofband noise at or near 1090 MHz. Portable or field ADSB monitoring to improve signal quality during mobile operations. Installations where multiple RF devices share the spectrum and isolation of ADSB signals is needed.
