I just hooked my SDRPlay RSP-1 SDR receiver up to an old-school vhf-LO, vhf-HI, UHF Roof-mounted TV antenna. I see ATSC Pilot carriers ranging from -110db to -58db on Chan 7,8,12 and 13 and then on various Chans from 15 to 36, with non-TV stuff above Chan 39.
I think this means that I need an antenna where the longest dipole elements are about 31 inches long(180MHz), and the shortest elements in the UHF corner reflector part are about 9 inches long (594MHz).
I would like a pretty good outdoor antenna to get OTA channels in my house. Anybody have any recommendations?
