Hi Gary, ok, glad that some of the numbers agree. I used NEC-Win Pro to
calculate the antenna input Z.

In real terms there is only 4 dB between our numbers for transmission line
loss, so not really a great amount. I am familiar with some of Reg's
programs, and have found them in reasonable agreement with other methods,
but have not tried his transmission line program.

The fact is, whatever the loss, the use of an open wire transmission line
would reduce the losses to near zero -- then he would probably find his
tuner could not match it!

Gary, since your data are so different from mine, you have to tell me
where
I went wrong.


Hi Frank, I used one of Reg Edwards Dipole programs to get the line loss.
At
the time that was the fastest way I could think of to get some numbers.
His
program lets you describe the antenna, feedline, and frequency of interest
and
it gives a number of operating conditions including line loss.
As far as where you went wrong? May have been me that was wrong. I
think I
have TL program somewhere, but don't have time to look at the moment. I
checked the impedance of the antenna a couple of ways, and it agrees with
your
calculation about 300+j700. The difference must be in the way the line
loss is
calculated?
