True. However, doesn't a 5/8 wave posses some gain over a quad element?
for better front-to-back, it's been suggested (and even commercially sold) to
add a reflector at the end of the boom, with a 50ohm resistor across the
elements. A 'dummy-load' to signals from the back side of the beam, and at
power levels on 2m such as most commonly 50w, it shouldn't be too hard to
find or build a 50ohm load out of several 1w resistors in series/parallel for
that power level.
