Give twinlead a twist every couple of feet and you save the cost of that
coax.
At the freqs used, most coax could be rather lossy, depending on the length
of the run, but twinlead has a very happy combination of being low-loss -
and - low-cost compared to most coax.

When it's new, when it's clean, and when it's dry.

As I understand it, one of the bigger downfalls of ordinary 300-ohm
twinlead for TV reception is that its performance can deteriorate
rather badly with age. Sunlight causes the PVC to deteriorate, and
surface contamination and moisture (e.g. rain) can significantly
increase the losses.

Coax is much less vulnerable to these problems.

It's also subject to problems if it is too close to things, remember those
special standoff insulators for it? It can not be looped, wrapped around things,
etc.

All,
I think the antenna has a coax connection built into it (One of
advertisements I saw). Also the previous wire was coax as is the rest
of the house. So I think Coax is a given for me due to simplicity and
never having any problems with it in the past. I will keep it in mind
though if something would change on the antenna or plans.

Thanks again,
Chris
