Marconi I like what I see and am impressed with your model showing an excellent pattern for the Sigma 4 with radials in your post #32 above.

I like the energy it appears to add over the NV4K in all the angles above 8-9 degrees. Looks like close to 3db in some angles while not losing anything in the lower 8 degree range to the NV4K.

That was part of why I was wondering what the shorter a99 radial kit would do because I've seen one of your models or one of the DBs models showing improvement on the Imax only with the shorter downward radials of the Imax kit.

I wonder if I should trust your model in post #32 to show what I'd actually get if I changed the NV4K to Sigma 4 spec with a longer radiator and a 90" cone with added 1/4 wave radials and hub from a Maco v58?

I don't mean I'm wondering if I can trust you & your modeling, I mean, can I trust the program to show me what I'd really be getting, enough to be worth the effort of pulling it down and adjusting?

It wouldn't be hard to extend the top section 8"-10" and slide the upper cone tubes down into the lower tubes about 15"-16".

Marconi you really have me thinking here. Might it be worth the effort?
