Hey guys
I know forms of this question have been asked a million times so I appreciate you guys bearing with me

I just moved into Bartram Springs (off Racetrack Road in south Jax). I lived not far from there off Greenland before.
I am now using an outdoor antenna for my HDTV reception. First off, does anyone use outdoor, specifically the type that attach to your satellite dish? Any experiences/comments/suggestions on quality? On a similar note, any suggestions on quality outdoor antennas? (ie: decent looking for the performance, heh)
The one I'm using now seems to perform very well, but there's an issue I noticed even when I used indoor antennas. Is there some reason that during the day I get breakup/pixellation on OTA but then at night it's flawless? It happened on my indoor antennas also even when I know they were in the sweet spot for perfect night viewing, I'd watch the Jags on Sunday and get breakup. Same thing happened today. Breakup during Jags but then that CBS movie at 9 pm was flawless.
Help me

thx@!
