Tom,

First of all, don't start at 2 P..M.  Eastern time tomorrow, you'll miss the 
first 2 hours.    Maybe I shouldn't tell you , so I can get the jump on you, 
but it starts at 1600 UTC,, or 12 noon Eastern.   Look forward to seeing 
you.


As far as a few feet having such an effect on swr, it depends on antenna and 
band, but sometimes just a few inches will make a tremendous difference. 
In this case, it's not so much  the length of your antenna, as much as the 
location of the feedpoint.   By only adding wire to one end, you have 
changed the  location of the feedpoint on the total antenna length, and now 
the various harmonics aren't where they  should be.   It's easier to add and 
remove wire from the ends than it is to move the feedpoint along it's 
length, but by  only adding to one side, that seems to be what you did.

I can't swear that  getting this thing balanced will solve  all your 
problems, but  it's probably  going to help.   You also mentioned guy wires, 
which could also  have an effect on things.

 Anyway, glad it works well enough to get by. Maybe sometime you can put it 
up with  ropes and pulleys or whatever to allow you to raise and lower it 
yourself at will.
