had same problem here also. I found that the 15 meter trap was the problem.
take a continuity test from bottom of the 15 meter trap to the top and you
will find that is dead short. of course take the trap apart from antenna
first, as you will have to take all apart anyway, meaning the heat shrink
and all, once that is done you will find 2 screws holding the wire from the
trap to the aluminium pipe of the antenna. take a file or sandpaper and
clean around the screw connections as that's where corrosion will form. I
use Vaseline in putting it back together. check your work as you go along. I
found some shrink tubing at home depot, it takes 1 inch diameter and 4
inches long. when all the work was done, trap looks as good as new, and now
works.ps..a good set of guys made from heavy fishing line or whipper nipper
nylon line, which you can buy in large roll really does keep the thing
straight.if you want to see my installation, I can send pics.will never put
up a vertical without some sort of support. let me know how you make out.

I boutght a used R7 about a year ago. Finally tried to get it up. It
matches on 10M but no where else. Any suggestions as to what might be
wrong?
