UHF RFI Filter For TV Signal Reception for HF 6m 2m 1.25m stations

This UHF RFI Filter For TV Signal Reception will block common mode currents from HF, 6m, 2m and, 1.25m ham radio stations and prevent interference with UHF TV reception. UHF RFI Filter will filter all HF and VHF signals below 300 MHz. Use this filter for UHF aerial antenna (roof antenna) and not for cable TV. All HF 6m and 2m frequencies will be weakened by 35dB or more.

The main application is to pass UHF signals (from 300MHz (470MHz) and up to 868MHz) or DVB-T, DVB-T2 signals and suppress all frequencies below 300MHz (HF, 6m, 2m, 1.25m). UHF RFI Filter must be placed just before the TV aerial socket with the shortest possible RG6 or RG59 cable (5-20cm).

The UHF RFI filter is composed of a UHF symmetrical high pass filter and common mode chokes.
