I assume the internal components were either part of, or reacting to,

if anyone else has had a similar experience, or if anyone has a better
understanding of the physics/electrical engineering issues behind the
problem.
The fan dipole is a balanced antenna. Coax is an
unbalanced feedline. Did you follow good engineering
practice and install a balun at the BALanced to
UNbalanced junction? I suspect you have common-mode
current problems (on your outside coax braid) which
a 1:1 current-choke-balun (or two) could reduce.
