I went outdoors, very happy with the Channel Master lineup, I got the "deep fringe" for around $90 give or take in 2005, not bad.
I think Lowes carries them, among the DIY stores.Channel Master line-up
The one I got, the "deep fringe", I love the name
I also got a pre-amplifier at the mast to boost my signal, this way when I split it among my HDTV/HD radio sources still strong and good quality signalChannel Master CM 0068DSB VHF/UHF/FM Spartan 3 Outdoor Pre-Amp
here is my antennaweb.org map, with my set-up I get ALL the digital stations listed.
I'm a fixed mast, pointed at 117 deg to get the Detroit stations.
Frankly, sometimes in very-very bad weather some of the off-axis stations pixelate sometimes, but not often.
Obvious, but I have to state this here:
To the OP (and others), be very-very careful putting up outdoor antenna on your roof.
I underestimated how dangerous this would be. My 2+ story garage roof is a 45deg pitch, at first I thought I could walk up that to mount it, WRONG.
I therefore had to get out my 32 foot ladder and use that to install the antenna at my gable end. Very dangerous carrying a fully extended antenna up there. I even used (2) 2 x 4' to securly brace the ladder to my home side so it would not move, a wise thing since while carrying the antenna up there and it swayed I'm sure the ladder would have fallen sideways w/o those.
My brother was there to help, but with only 1 big ladder he could not do much, if we had 2 big ladders would have been so much safer, but who has two big ladders at home?? I have the one 32 footer because every 4 years I have to re-stain my log home on the outside.
