I don't think so, only because I have seen flat ground planes. My Starduster
were at a sharp angle. Maybe Scott can knows better. I would think the flat or
GP at 90 degrees to the center conductor is fine.

Straight radials would create a 30 ohm antenna.
45 degree droops create about 50 ohms.

How come I use to see both during the CB era? Radio Shack made a ground plane
with straight radials.



There shouldn't be any current flowing down the outside of the
shield with a groundplane, so you won't need a balun,

There you go. That is one less step !

unlike a dipole that requires equal and opposite phases.
If you try to feed a dipole with coax, the outer shield
becomes part of the antenna system, causing high SWR readings,
(even if the SWR is low), RF interference and degraded performance.


Thanks, for the info.
