The loss in 100 ft. of open-wire line on 4 MHz is so low
it isn't even on the chart. :-)

=========================

The loss at 30 MHz with a very high SWR is on MY chart.

And the loss in properly used coils is very small.

But either way, the difference between the two methods is so small you are
unfairly claiming an advantage in the use of transmission lines. Do some
accurate calculations to see what actually happens.
