It looks just like a standard 1/4 ground plane, single vertical
radiator, three (typical) horizontal elements perpendicular
to the vertical element.
The Vertical Radiator is 5% shorter than the horizontal elements.
At the base of the vertical radiator an 1/8 inch Aluminum Rod
is attached with screw hardware and extends out perpendicular
for X-inches (length of the Beta depends on the frequency of
intended operation), then bends down for a a few inches followed
by another bend and return rod length back toward the antenna
base mount (ground) where it is attached (grounded) with another
screw nut hardware combo. It's that simple...

Satisfying your curiosity is a daunting task... I didn't
think the Beta Match up, I lifted or stole the idea from a
commercial antenna product I purchased back in the 1970's.
You can model this antenna using EZNEC if you have a copy. I
found a public domain version is supplied with the ARRL Antenna
Handbook (on the included CD) if you have one.
Age sometimes has its rewards...
