havnt done antennae for years but look into Wineguard. I think
they still make them here ! Whatever you do get the biggest you can.
In the good old days I ran a Jerrold VU937 IIRC. Twas a beast
20' long & double boomed. From 25mi NW of Boston could get UHF
out to Me. & a ton of them from Ct & W. Mass. . VHF was fully covered including 2 ch 6-8-13. 6 was New Bedford or Portland 8 was New Haven
or Mt. Washington NH. 13 was Portland or NYC. At night when stations
went dark could get all the NYC VHF's & half the time ch 3 Philly.
I wasnt even up high ! Try that with HD.
Boy do I miss NTSC
