76Q, here are some variations for radiator and top hat lengths for a 1/4 wave radiator. I used slanted down radials and one model that is full length and slanted down radials, and one model that is full 1/4 wavelength using 4 x 108" horizontal ss radials.

I also have a model of a simulated mobile, but I don't think the pattern is near what you might expect, so I didn't include it. I'm not even sure it is a good model. It shows to be workable however. I used the 4 horizontal radials and made 2 x 6" x 4' and 2 x 6" x 8'. I will work with it a bit and if it looks promising, I post it later. This may prove to be futile however, because mobiles have a very unpredictable ground plan with variations and curves that are irregular and may be difficult for me to model.

The numbers at the end of the captions are the length in inches for the radiator and the top hat including a little space for the feed point hub.
