Not necessarily. There's some excellent work reported in one of the
ARRL Antenna Compendiums showing that window line is quite lossy
when it's wet.
I suggest that you (and anyone else who thinks a balanced feedline
makes a balanced antenna study my RFI tutorial and the associated
Power Point on Coax Chokes.

ANY antenna without a REALLY GOOD common mode choke at the feedpoint
can be quite noisy on receive. It's not very practical to put ANY
common mode choke on a balanced feedline, let alone a REALLY GOOD
one.
