Which one of the the two is more efficient as a radiator & why?

1/2 wave vertical fed in the center with coax or one vertical 1/4 wave
with four 1/4 wave radials also fed in the center with coax?


The vertical dipole has more horizontal gain than the groundplane.
I believe its about 1dB improvement.


Actually, *neither* one has any "gain". :-)
