Additional loss occurs in the tuner which may be greater than xmsn line
loss. QST has had measured losses for various commercial tuners as the
subject of 1 or more articles. The losses on low bands and certain
impedances can be a significant factor. 73, Dan, N5AR

Essentially identical.

Are you making some assumptions here? What is I have a perfectly resonant
coax fed dipole at 3850 KHz at 140 feet and run 200 watts CW. Now compare
this to a 30 foot long piece of wire at 20 feet fed directly with a tuner at
the same frequency. Is ERP affected in this case?
