"Old Ed" asked -

What parameters does a user input into your newly-posted program
in order to estimate tuner and/or balun losses?

=========================================
Ed,

Program LINELEN's primary purpose is to calculate the impedance
presented to a tuner.
(snip)
The program cannot predict tuner losses. It has not been designed to
so.

Reg,

Thanks for the clarification.

I might note that it's easy to see where I got the idea that LINELEN
attempts to calculate tuner loss. Your first post in this thread had
the subject line "New program. Dipole +Line+Balun+Tuner"; and
it included the line "Power lost in antenna and line is calculated.
*Also overall loss.*" In order to predict *overall loss* of the chain
described, balun and/or tuner loss would have to be included.

From the balance of your remarks, I conclude that you (like me)
don't think that accurately predicting the losses of real-world
tuners is a very practical undertaking. (Sometimes empirical
measurements rule.)

I hope many find your program useful for what it IS designed to do,
and thank you again for making it available.

Ed
