I use that commercial 450 Ohm windowed ladder line for
moderately long runs to wire arrays. I cut out every
other spacer with a pair of scissors and rub high
quality paste wax over the feedline. The water runs
right off in the rain and the Z seen at the transmatch
hardly changes between wet and dry. The wax lasts for
years. I think.
Real open wire line is better but I don't have time to
make four hundred feet of the stuff. I take the time
to make it for phasing lines and matching stubs that
are kinda critical however.
