Default Want to replace old flat tv cable with better coax.

JG,

I agree with everyone here that coax is better but so far noone has
mentioned there are two types of coax, 50 ohm and 75 ohm. Make sure
that you use the 75 ohm coax. 50 ohm is generally used for
communications and you can't tell the difference between the two by the
size or thickness of the coax. You can tell by the number stamped on
the coax, eg. RG75U, etc.

I have done some reading about balun transformers and how I can connect
my existing flat antena cable to 75 ohm cable.

However, my questions is this... what if I replace the 30 year old flat
cable all the way to the antenna. Will this yield better reception?
(It is pretty good as it is.) The exiting flat cable is starting to
fall apart at some places. Currently I just have it directly wired to
my coax cable (just before it enters the house) with out any type of
transformer. The coax is properly grounded (to the circuit breaker
box.)

So my questions are these:

1. How do I connect the coax directly to the antenna? Or should I?
Do I still need a balun transformer?
2. If I need a balun transformer, does anyone know of a heavy duty
outdoor one? (Or should I build my own.)
3. Will reception improve?

Thanx to all who reply.
