Default Vertical ant gain vs No radials

CORRECTION - I mean to write 90 radials rather than 90 verticals!!!


Heh heh. There does come a point, though, where more verticals will
achieve the same result at less expense than more radials. I've found that
8 radials of about the same length as antenna height works well, even with
multiband antennas. And a second antenna will recover the gain to the same
level as 120 radials (standard broadcast design), plus providing a
steerable pattern. Coils eat up as much and can be eliminated, or made
smaller with top-loading capacity hats.

Or, for radial-free performance, design it as an end-fed half-wave!
