If your antenna system is good enough so that you get strong signals
from your desired stations you will have no problems. If you have
marginal signals you will get breakups on digital signals. I don't
remember what happens on analog because there's just one analog
station I can receive here (W36AZ ch 36) which I can get in digital
anyway. I operate at around 800 watts and there's no interference on
my TVs.

This is my TV antenna setup -

2 x Channel Master 4228 (16 bay bow tie array, with a reflective screen) for UHF
Winegard YA1713 Yagi for VHF 7-13
Antennacraft 10G212 30dB preamp

The antennas are about 65ft on the tower which is good enough to get a
digital lock and no dropouts on the NYC stations which are ~49 miles
away. Only Fox 5.1 WNYW-DT has a little tiling when I key up because
their antenna pattern I think reduces the signal towards here because
of co-channel with WMCN 44 in Atlantic City NJ.
