My antenna designs do not need a balun because I use
a modified version of a feed called a Gamma match that feeds the
antenna at the fifty ohm point...

Hmmmm. so this is a fellow with another antenna design, bad-mouthing the
opposition. It makes about as much sense as my giving you this advice:

"If you were planning to go with Bob Archer's design, don't bother with
the gamma match lengths he uses..."

What DOES make sense, is that if you really do follow Archer's advice to
rig a dipole hooked directly to the coax - you guarantee standing waves
on the outer (sheath ). A balun is what matches this dipole
arrangement to coax...
