Again MythTV officiados swear by the cheap "bowtie" models.

Whatever you get, you have to keep it away from metal and other wiring
-- at least twice the width of the line. This is because the electromagnetic
field extends into the air around the conductors, whereas with coax it's
contained within the shield.

Also, twinlead is prone to "ingress" problems, signals that exist in the air
will get into the twinlead and cause interference, front-end overload of the
receiver and other problems.

This sort of problem is somewhat reduced by phase cancellation of a signal
which "ingresses" into both sides of the balanced twin lead equally, but it's
still a problem.  Coax, being shielded, is resistant to the ingress of outside signals.

Generally twinlead works well in "quiet" electromagnetic areas like rural
areas, but is problematical in urban areas with a lot of RF floating around
the environment.

So, it's safe to say, that the whole antenna installation needs to be
evaluated for signal loss, rather than a simple replacement, where you probably will
find that the same interference and electromag RF causing grief?

Try an $8.00 antenna!
Search the internet and you will find instructions on building an HD
antenna for $8.00.
I live in the west valley and gave up cable t.v. about 3 years ago. I
have rabbit ears made by Phillips which
cost me about $70.00. I purchase all the parts for my $8.00 antenna but
I have yet to build it. I have Rabbit ears on my t.v. up
at Sedona and that works better without the HD converter box?

Here I use the convert box and its ok. But I am looking foward to my
$8.00 wonder.
Good luck
