Re: OT: What is the best antenna for getting Phoenix area TV…

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?
