Hi,

if I understand the common mode discussion correctly, a short
(not necessarily active) antenna and a much longer feedline
act together as kind of a dipole. If I connect my receiver
with a very short feedline (say 1m), to the antenna, I should
not be receiving much common mode noise. Is that true?
Certainly worth trying.
