Re: Patches and BB Grills

Tony's answer seems correct...but has anybody ever tried it?

If the grill elements are close enough together, there must be some point at
which the dish looks "solid".  At that point a grill should perform much
like a solid or mesh dish, even with circular feed.  If that's true, I
wonder what that dimension is (for 2.4 gHz)?

Just curious.
