be about 18 feet long. Not 9 feet or 11 feet 6 inches.

He is also mislabeling the names of the various antennas, and
makes it hard to tell what the heck he really has..
A Ringo Ranger is a VHF or UHF antenna, and is a twin element
collinear vertical. It has a phasing stub type deal between the
two elements. The 2 meter version happens to be about 8.75 ft tall.
A Ringo is a single element halfwave vertical. And Cushcraft does/did
make a 10m version. It's the AR-10, and is appx 16 feet tall.
So I'm starting to wonder if they are using a 2 meter antenna for
10 meters.. ??
It would be fairly easy to convert the RR to a 10m ringo..
Extend to 16 feet, and you would need to use a larger gamma loop,
and a bit longer piece of coax for the capacitor.
I've made them before, and used 1/4 inch copper tubing to make the
gamma loop.
BTW, a 10 meter ringo does not require radials. But it can be
further improved by adding a decoupling section a 1/4 wave down
from the feed point. I used a union to ground the shield to the
metal mast at that point, and had three 1/4 wave radials.
