There is no need for a low-VHF antenna unless you want redundancy. Both translators that show on low-V are too far to the north anyway to be picked up reliably on a 2-69 antenna aimed to the west.
All the translators you need, plus your local channel 10, tranmit from Grindstone Mtn. A simple 7-69 antenna ( I suspect most UHF antennas would also pull in KENV anyway) pointed at 265 magnetic will do fine. You could point the same antenna towards Lamoille Summit and get most of the same programming, probably only missing the translator for KENV.
