re: #154 The Very Reverend Battleaxe of Knowledge

They used to sell a little high-pass filter you could plug into an outlet and attach your TV’s leadin to it, to use all your wiring as an antenna. I never tried it, because it seems like that would be completely omnidirectional, which is the absolute last thing you want in a TV antenna.

Well, that depends on where the television stations are located. Recall that VHF TV antennas were sold as these boxy square things which were omnidirectional. Rotating directional antennas are a whole lot more expensive.
