My favorite example of this was a visit to the TransWorld Radio
shortwave
site on Bonaire (PJ4). They had a 50kw broadcast station driving their
750kw final and the curtain array (14.5 Mhz) was (is still?) fed with
open
"wire" line using two parallel runs of 4" aluminum irrigation tubing (or
what looked like that) for the conductors...
