For horizontal wire antennas, it is indeed good to have a good height. I will try to put it higher, depending on the available options.
Watching TV from other countries was a hobby at that time.
I heard about TV DXing. Many people are doing the same with the broadcast radio stations too. Sometimes me too. You can find the video recordings of receiving various broadcast radio stations from around the world on YouTube. We do the same on the radioamateur bands in two-way communications, so we both receive and transmit too. Good to call CQ (general call) on the radioamateur bands, and it is often a surprise who will answer it.
