Base Have a look at this Antenna

Eddie,
did what you had to do to the model in order to get that downtilted pattern fit how you interpret what is meant in the patent by making the radials parallel,

does eznec agree you get downtilt over real earth? or is this free-space.

is the parallel setup more sensitive to mast length below the hoop.

I guess its time the resident MacGyver strung some wire wood foil & tape together

(Edit)

Yes these models are all in FS if we see tilt. I have not seen downward tilt over Real Earth.

I just tried making the regular A/P design in FS with a longer radial mast and it does not seem to effect the tilt for sure. It might tend to make the tilt rise however. I will have to play with that idea.

Homer, when you do like Bob suggested, be sure and 'splain to us how you determined the effects, without using smoke and mirrors, OK?

I'll see if I can squeeze it into my schedule.
