Hi Irv,
The 300 ohm TV line I am sure works, but it does not appeal to my tendency to
want to make everything "industrial strength" as if we were all going to live
for ever. I am finding it difficult at the moment to resist the idea of
making my ladder line out of #10 bare copper, thus insuring I will have a
*&^%$#@!!!!! time up on top of a ladder yelling and screaming things like
("why do I always make things so difficult) hi hi. Actually I think that the
#10 bare copper ladder line with my secret hardware store insight spacers
will look impressive.... (who am I trying to impress is the question) I need
to get my butt on the air otherwise I be only a "theoretical" ham.....
Secret hardware store spacer insight: the 4" uv/pvc ferrules that come with
the gutter spikes!....no I didn't say gutter snipes.....hi

everyone was working this guy in Lithuania on 20m this morning....can't wait
to get in there...... fun.....

I am now thinking: how bad could those commercially manufactured
window lines be?
Any recommendations on a specific type of commercially made window
(ladder) line?
I used 300 ohm TV twin lead for years. Why the concern about 600 ohms? It
really doesn't matter unless you have a 600 Ohm feedpoint. The losses are
still very low regardless of conditions, and as for dirty or rain, I had
some up from 1983 to 1996 -- and never noticed any changes. When I took
the antenna down the twinlead was as good as new and I used it for other
things.
