The G5RV has been said to radiate from the feedline.

Only if it is unbalanced (such as not installed sysmetrically).

If each side of the dipole is bent asymmetrically, then very little
imbalance in feeder currents is evident. Off center feeding a dipole does
unbalance feedline current. A double extended zepp is a good example of an
unbalanced feedline with significantly different currents in each leg. It
would be interesting to see just how much power is actually radiated from
the feedline of such an antenna.
