It makes no difference how the tower is fed, a vertical antenna must have
radials of some kind to be effective. 73. . .Dave, W0FLS

Subject: Topband: Use shunt fed tower
A shunt fed tower is a vertical antenna so it offers lowest take off angle.
Shunt feeding avoids need for radial field. Any horizontal wire antenna is
going to put most of your radiated energy out at high angles, unless you can
get it at least a half wavelength of height. A loop may be a quieter
antenna for RX but your existing inverted Vs are no doubt better for TX.
There is some art and experimentation involved in the matching but the
results will be worth the effort. I would start with your highest antenna
for top band, next highes for 80m. Note that your yagis will act nicely as
capacitive hats to add to effective tower hight.
