There is no extra mast. You are using the support mast
below the feed point. The extra parts are a 50 inch length
of coax, and a union to support a set of 20 inch long radials.
The radials are connected to the shield of the coax.
Years ago I converted an original Ringo Ranger to a
Ringo Ranger two using home brew parts.
I then did comparison tests with and without the radial
set. Made a huge difference in performance in my case.
Cushcraft seemed to consider it a third 5/8 WL element,
but I tend to consider it a decoupling section much
like the lower cone you see on an Isopole, or using
a 2nd set of radials or cones below a ground plane.
Yes, it is worth converting. The ARX2B is a pretty good
antenna. Not quite as good as the Isopole, but close.

I have seen people swear by and swear at Ringo Rangers. Is this
because of by chance some people get the right/wrong length mast and/
or coax length?

That could be the case with the non decoupled version. :/
But the RR2 is a pretty good antenna. I used one for a long
time and never had any problems.
The mast and coax length could be fairly critical on the
non decoupled version.
Like I said, I converted an old ARX2 to a ARX2B and then
compared the two when receiving local signals.
The difference in my particular case was quite large.
I'm talking 2-3+ S units on the radio meter which
actually would be a huge difference. It was quite
apparent that the common mode currents were really
whacking the pattern on the one I tried without the
decoupling section. I assume most was from the feed line.
