My experience with OTA digital vs analogue is similar to Mike Dean's.
I am shadowed by at least one intervening mountain from our local vhf
and uhf stations located about 25 miles away in Missoula, MT. VHF and
UHF analogue reception was possible with many ghosts using a modest
Radio Shack combo uhf/vhf antenna in the garage attic.
Digital was hit and miss until I purchased a four bay bow tie uhf
antenna and mounted it outside on the garage roof. Now I receive all the
digital uhf rock solid. My experiments showed that outside mounting is
clearly superior to an attic mount. The bow tie is a sturdy antenna so
it should last a long time even mounted outside here in Montana.
I still use the radio shack combo uhf/vhf located in the garage for our
only local vhf digital (Yes they do allow digital on the high band vhf
channels.... ours is KPAX-DT on channel 8 ( and 7 analogue).) I use a
combiner to mix the output of the bow tie preamp and the RS combo preamp
so I only have one RG6 cable run to the garage attic.
So if you, or any of your neighbors, can get a "watchable" analogue
(no sync tears or drop outs), I'd say it's worth while to try a very
high gain uhf antenna and low noise preamp then mount it as high as you
can possibly place it. You just might be able to get digital OTA.
Out here, I'm not served ( or even dis-served) by cable, and no
prospects of ever having cable service so OTA was the only option.
