That makes sense. Thanks for the tips.

On page 16-23 of the ARRL Antenna Book, 19th ed, Figure 35B shows a
very simple vertical J design. It's open-stub, direct fed from (in
fact, pretty much made out of) 50ohm coax, with a 3/4 wave length of
core conductor and a parallel 1/4 wave wire coming off the shield.
Looks almost too easy... any thoughts on how this would compare to the
1/4 wave whip with ground radials? It's got a larger aperture, but I
don't understand how the grounding is meant to work...
