If you're talking rabbit ears, I'm not surprised you see a difference.
They're a rotten antenna system.  But I'd be very surprised if you don't
see some other nasty problems with your digital reception (freezes,
blocky picture breakups, etc.).  A bit of snow, even ghosting, is still
bearable on analogue TV, but digital TV that breaks up and loses sound
and picture once every 20 seconds (i.e. repeatedly) due to poor
reception issues is unbearable.

In my case, I have a proper external antenna aimed directly at the TV
towers about 15 km away (belting out a few hundred KiloWatts), with no
obstructions, and it's correctly wired.  I used to have near perfect
reception, almost like I'd plugged the studio camera directly into my TV
set.  I can't say the same for digital.

Standard definition is poorer than analogue, even HD is pushing its luck
(if you take into account that when you digitise something you need to
sample at least three to four times the frequency that you're sampling).
CCD video cameras are often worst than tube cameras, for that same
reason (resolution issues down to the low number of pixels involved
compared to a 700 line resolution camera).
