Yes. It is VERY well known (that is, long ago proven science) that
radials affect the EFFICIENCY of a vertical, while the ground in the far
field determines the vertical radiation pattern, especially the strength
of the low angle radiation. High conductivity => good low angle field
strength, poor conductivity => poor low angle field strength. Again, the
ARRL Antenna Book and ON4UN's book are very good on this topic.
