Looking for a design for a multi-element (10-20) yagi antenna that I may use
for sending/receiving wireless audio/video used for surveillance system.
Not having the best of luck finding same at this point.
Any help for one's already designed or a good formula to go by to build my
own.

Thanks,
Mitchell

Hi Mitchell,

Why do you need that many elements?

When higher gains are sought, other approaches are more effective, for a given
form factor, than a Yagi-Uda.

What gain/beam do you need?
