I feel the best compact antenna choices for your situation would  be either the 
ANT-751 or the 
Winegard 7694. Either of these models should easily power 1 TV with 75 feet of cable without the need for amplification. I'm afraid the HD-1080 may not have enough gain to provide reliable reception on your 2 VHF channels. Hopefully others will chime in with other suggestions.
Others here are also best at suggesting possible mounting scenarios, so I will leave that to them.
Good luck!!
