Frequency : 45 - 860 MHz
Channels : VHF 2-13 UHF 21-69
A quarter-wavelength on channel 2 is roughly 1.5m or about 60". Any
antenna whose largest dimension is 21" is going to be very much a
compromise on VHF.
"Up to 50 miles", kinda suggests that if the VHF station is operating from
a 2,000-foot mountain, you're on a hill too, there are no noisy
computers in your house, and the atmospherics are just right, you might
get a snowy picture. I would suggest that in "real life" 10-15 miles
might be a better estimate, at least for VHF.
