Good Luck with your 8 barrel feed system.

Yagi design is not just about the feed system. There is an interaction
between the feed and the tuning of the Yagi. Especially the driven
element and reflector. While computer modeling is nice to compare.
Nothing beats taking the antenna out to a certified antenna range and
measure the performance.

Matching networks are just that. Simple designs work just as well as
very complex designs. Yes dome designs do minimize pattern skews, but
for amatuer and CB usage at 30 MHz. and below, you are not going to
get that tight of a beam pattern to where pattern skewing is a major
problem.

I didn't realize that they still made the moonrakers.
