That seems to be my real world also. I have not seen
that much maximum range as the the power or antenna
gain goes up but it does seem to fill in some of the
local holes beter. In the 70's there were some 6 foot
long whips for 2 meters. If you could stop the car
you would usually get slightly beter range or signal.
While in motion they flopped around so much the 1/4
wave whips would out range them. A good stiff antenna
would out range the floppy ones that were longer and
had more gain.
The area I am in (North Carolina) is full of low
hills. The repeaters were usually about 300 to 800
feet HAAT at the time. We did some antenna changeing
on the same car and it depended on the direction the
car was facing and the repeater as to what gave a
beter signal. Sometimes the 1/4 wave beat the others.
On one repeater a 40 meter antenna mounted on the
bumper beat all the others.
