Back in the early 00's when we still had analogue VHF TV signals, we wanted to watch the football world cup at school. Of course there was no cable or anything at the school and no VHF antenna and streaming was not a possibility yet so we had to be creative. We found an antenna cable and tried to manipulate the cable and use whatever as an antenna. We tried the sheet metal roofing, but that didn't work very well, we tried some metal rods and that didn't work great either. By chance we found out that if someone held the cable in one hand and leaned out of the window with their other hand stretched out we got a signal that was good enough to watch the game. Well, for everybody except the poor bastard that had to stand behind the TV halfway out the window.
Fond memories here of watching Babylon 5 on a Performa 5300 with an Apple TV Tuner Card. There was no antenna to the room with the computer, but I found that I was able to get an acceptable picture by holding the coax cable attached to the antenna input in the right way while keeping one hand attached to the central heating radiator...
