[TenTec] Wet ladderline -- Comments on QST report

[Steve Hunt]

That's probably close enough for this sort of work!

But it's maybe worth pointing out that an unmatched line does not have 
uniform losses along its length - the losses are higher at the standing 
wave current maxima than they are at the minima. On a line with an SWR 
of 6:1 the losses at the current maxima will be 36 times those at the 
minima. So, for accurate calculations on an unmatched line, you can't 
simply scale the losses linearly with length.
