I tuned up on
the dummy load, then switched over to the real antenna and checked the
SWR. Here's the results:

Frequency Dummy Antenna
3.750 1:1 infinity
7.150 1:1 2.5:1
14.175 1.05:1 3:1
21.225 1.1:1 3:1
28.850 1:1 1.9:1

Jack,
I don'r have any experience with the noise bridge, but based on the SWR
readings, I would do the following:

Since you have no 80m radiator, ignore that band for now. Measure the SWR at
7.0 and 7.3+ to determine whether the 40m wire is too long or too short, and
trim to size. Repeat at 14.0 and 14.3+, and 28.0 and 28.5(?), assuming you
want the most used part of 10m. I guess you are useing the 40m radiator on
15.
