I understand that there's no such thing as a "HDTV" antenna and the name is all marketing hype. At it's heart it's still just a dual band UHF/VHF antenna. So my question is, can I build a simple dual band j-pole, connect it via RG6 to the ANT/Cable input on the TV and actually pick up OTA broadcasts? Would it need any modification? I've seen some folks mention needing a 300Ohm IMT on their homebrew antennas.
