Of course! When raised, the Q of the antenna system went up
as the ground loading resistance decreased, particularly on the
low bands where the E field ground penetration depth is quite
high.

I presume that what you saw "improved" was the width of
the vswr curve; again, you saw only the result of adding
series resistance into your RF antenna circuit.

Yes, you probably were loosing up to 5 dB of your rig power
in hearing losses in the ground resistance, probably especially
during dry weather.
