I do like some low VHF Channels like WNWT-LD (Story TV and history) so guessing I'll need long antenna. Will Classic Series Yagi YA7000C be a good fit or something else? Also is my mounting location ok?
I find it really hard to believe that antenna can do Low Vhf, plus they are gouging you on the price, but it's worth a try if you are willing to pay for it.
As for is your mounting location ok, that's impossible to tell by guessing. Mount the antenna with as clear a view too the towers as you can get, and see what happens. If it doesn't work, put a long coax extension on it, and move it around to see if you can better the QUALITY of the signal. Sometimes a foot up, down, or side to other side or so can make a REAL big difference.
Signal STRENGTH is not the end-all, sometimes a lower strength BUT higher Quality can be better, yeah that's possible to do in some cases. Peak the signal quality as much as you can on the particular stations you want the most.
P.S. I just checked the feedback comments on Amazon for Low VHF for this antenna, and they seem like it's working out ok for the most part. Buy it from Amazon, and if it doesn't work well enough, you can likely return it for a refund if you don't scar it up badly while installing
