To address the challenge of severe interference from 5G base stations, PBI has released the new C-band bandpass anti-5G interference filter, model WFP-3742-10. The WFP-3742 BPF (Bandpass Filter) has undergone rigorous performance and environmental testing, as well as actual field tests involving 5G signals. Test results indicate that the WFP-3742 BPF can reliably and effectively protect existing C-band satellite services from interference caused by adjacent frequency carriers. By utilizing the WFP-3742 BPF, users of C-band satellite services are expected to benefit from uninterrupted operations even amidst widespread 5G deployments. The WFP-3742 BPF filter has obtained the network access license from the National Radio and Television Administration (NRTA), authorizing its legal and extensive application in radio and television projects.

Installation Guidelines

The WFP-3742 Anti-5G Interference Filter features a standard CR299 interface; installation is non-directional (no front or back).
Do not remove the protective film covering the interface during installation. This film does not affect signal transmission and serves to prevent dust and foreign objects from entering the cavity.
Ensure bolts are tightened securely during installation to guarantee a tight and robust connection.
