length of 10 feet.

No, you didn't! You responded with a antenna
length of 11.775 feet, 3.775 feet longer than the agreed upon
8 foot antenna. It wasn't the whip that was to be 8 feet, it
was the entire antenna. I made that perfectly clear early on
so it would match the mobile antennas in the ARRL Antenna Handbook.

You did not acknowledge the changes you made until I complained.

Of course I did. Go back and read my postings about such.
It wasn't until you complained that I sent you the corrected
EZNEC files. I made a severe blunder in the traveling wave
model and you copied my blunder.
