I would rather that the audio stutter as it would still be audible. Yes,
it
would still be annoying, but I find the complete lack of audio even worse.

Well, my additional testing shows that it is not so much an antenna
problem
in and of itself, but it is also room issue, TV location issue (against a
wall and probably not close enough to a window) and also more than likely
not enough gain (as mentioned in a previous post) to boost the signal in
the
problem room.
In the room with the reception issues, neither the TERK TV-5 nor an
RCA ANT-401 nor an RCA ANT-200B antenna can hold a stable picture for more
than 30 minutes maximum before some sort of video corruption occurs, which
results in the audio dropouts. In two other posts, I have mentioned that I
did find an RCA ANT-200B antenna position that will hold a signal without
errors for up to 2 hours.
However, in another room, OTA DTV is being received with almost no errors
unless I stand right next to the antenna. That TV is closer to a window,
and
the antenna in use is a TERK TV-5.
