Thanks for the response.

Yes - the C31 is about 1.5 ft above the top of the tower. The guys, four of
them, are attached directly to the metal plate at the top of the tower. I
have an insulator in each guy about 14 ft from the top of the tower. The
problem I am experiencing is not being able to get the SWR on 20 and 15 down
within spec. I have exchanged a number of emails with Natan at F-12 and he
figures the problem is related to the fact that the 14 ft guys sections
electrically connected to each other via the tower plate (about 1.5 ft
across) is detuning the C31 and causing the swr problems. Oh and I do not
see any swr change as I rotate the antenna.

Any advice before I endeavor to make a change is really appreciated.
