[Elecraft] OT Wet 450 ohm ladder line

[Geoffrey Mackenzie-Kennedy]

Sorry for an off-topic question. Does anyone have any information about the 
dry vs wet characteristics of "450 ohm" ladder line? I have never used this 
type of line, but I might have to use it for "mechanical" reasons to feed 
another antenna now being built. I am told that its characteristics change 
when wet from rain, but which characteristics change and by how much at HF. 
A remote ATU to compensate is not to be used with this particular antenna / 
feeder.

Any comment would be appreciated.
