Hi, all concerned:

Is this the balun problem?

For openers, a 40-meter half-wave dipole with trees and 3 dogbone
insulators, center-fed directly across the center insulator with 33 feet of
RG-59/U coax, nothing special,

coax

33

you know, like that ASCII sortagraphic. Like the one I put up in 1957 or
1958.

The thing has voltage loops at all ends, including the shack-end of the
coax-braid, correct?
