If your looking for a mostly foolproof construction for a homebrew 435
MHz satellite antenna and have access to a 3D printer, you might check
this out. It's a weak choice for general 70 cm terrestrial use, but
I've had good results on it for various satellite passes that require a
high elevation pattern. It can't compete with crossed yagis and an
az/el rotator, but it is an easy and inexpensive way to get started.

My video and narrative skills are clumsy so please take that into
account if you watch it.
