Thanks for the reply and example John. I was referring to the loss in
power when operating into a high SWR with coax VS a high impedance
line like twinlead / ladder line / open wire. Someone in a post here
mentioned it was mainly current losses and that piqued my interest.
Cecil answered my question and gave me the formula. In his example the
coax was carrying about 3 times the current of the 450 Ohm ladder
line, which explains it.


Remember, that is for the *SAME SWR*. When the SWRs are different,
as they will be for a fixed load, that loss ratio figure will vary
away from 3 to 1.
