HPF-50-55
TVI High Pass filter
The HPF-50-55 is a high pass filter designed to remove interference to susceptible television receivers. The filter offers a very high level of attenuation against strong out-of-band signals which may be present at the input to a TV from a local HF transmitter - your amateur transceiver.Greater than 80 dB of attenuation is provided in the HF bands below 7 MHz and for the majority of the HF band the attenuation is better than 60 dB. The pass band ripple is kept to below 3.0 dB for frequencies below about 300 MHz ensuring that there is very little attenuation of the wanted TV signals. The filter is supplied with standard "PAL" type connectors, one female and one male so that the filter is easily inserted into the feedline between your TV antenna and your TV set.
