I'm sitting outside of Tampa right now and with my Jack antenna, mounted on my old crank up mast, I just counted 62 channels. Some were even in English and a couple of them were not trying to sell me something. I got all of the network channels, several religious channels, several cooking or home improvement channels, a few educational channels, children's channels, etc.
Basically the antenna was extended and faced in one direction when I did a scan. After that initial set-up, I did not have to move the antenna again to pick up 62 channels.
