I think that everyone on this forum has missed the point.
The op does not understand how antenna's works, is stuck in the CB radio and won't listen to reason.

A 9' long Ringo is 6 meters - 50 MHz.
It is also a 1/4 wave antenna for 27 MHz but will not work for 11 meters, because the impedance is all wrong - almost 5:1 VSWR....

When you shorten a antenna that is designed to work on another frequency, the design has to match in order for it to work and have the right impedance and be resonant.

A full wave antenna, other then a dipole antenna is not a balanced load.

The ring on the Ringo is the match, and the ring is around 32 inches long.
You have to subtract 30 inches from the total length - which a resonant antenna would only be about 40 inches long.

That doesn't leave much of a stub sticking up for a vertical radiator.

I gave away a HALO antenna for two meters, for working SSB and digital modes and the diameter of it was only about 24 inches.

Making a antenna is not as simple as just sticking something up in the air and connecting the coax to it and cutting off the excessive length and expecting it to work, like a mobile CB radio antenna........

Who was it that said, you can't fix stupid!

Buy a 2 meter antenna, forget about trying to make something out of your CB radio crap to save a couple of bucks.

What you could do is buy the ARRL antenna book and make a 4 element beam antenna out of the antenna segments of the Ringo if you had a piece of box tubing - antenna boom and a Gamma Match..
