HPF-50-55
High Pass TVI filter
The HPF-50-55 is a very effective 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. The TVI filter is designed for coaxial cable (75 ohm) TV antenna systems.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.
MORE GOOD NEWS! The HPF-50-55 has also been found to be effective at reducing the amount of interference PLASMA TVs create on the HF Bands. Customers have reported significant reduction in HF interference to their receivers when a HPF-50-55 was fitted to those pesky RF emitting PLASMA TVs.
Want to Try it Out
Buy a Rippletech filter and if it doesn't fix or help your TVI or HF interference problem, simply return it and the packaging in good order and we'll provide a full refund of the purchase price (less postage which is usually only $2.00). Effectively, you can trial out a TVI/RFI solution for as little as $4!! How good is that?
