One thing you could try is using the latest drivers from the
linux-v4l2 repositories.  They're constantly improving things, the
ones that ship with the kernel tend to be pretty old.  I'm about 30
miles from the transmitters but in a very urban area so my signal
seems to be pretty good for most channels except NBC.  I have a 4
bow-tie style UHF antenna.  Could your splitter be bad?  Perhaps you
need to try the feed out of the 5500 on your TV and see if isn't just
a bad cable.
