TVI cure

Just 100w and a wire is enough to interfere with our Samsung smart TV.
I tried a few high-pass filters but none would pass the TV OTA VHF channels.
Then I got lucky. A couple more bucks than a simple high-pass, this band-pass filter keeps HF out of the TV, and everyone happy. (ASIN B07Y2SFN1M)

I'm sure that there must be other filters that keep amateur HF+6 out of the family TV, but this is the first one that works for us.

'Tworks! Well, mostly.
The weak TV signal on Ch 23 was protected with all the others, Ch 6 - 65, but only this weak TV signal blanked when i transmit 100w on 20m only. Other bands seemed no problem.

The cure so far is another filter, just like the one on the TV in the previous post, but now also a filter at the TV antenna wall plate.

We now get some 60 OTA TV Ch and I can play radio! What's not to like? :D
