In due time the dirt which comes down with the rain will also stick
to a vertical run of twinlead, thereby gradually obviating an initally
acceptable performance.


Two years and my twinlead still sheds water like a duck.

At least in my case, the short time that I have been a Ham, I have seen
more problem with water in coax than I have seen water problems with
twinlead.

But we knew about those problems because the antenna didn't lose a bit
of signal. It simply quit working at all!
