The delay section of the super-J does not have to be made of twin lead and does not have to be a flat extension! It can be curved around the radiator. It will work fine. It can be made of stiff copper rod curved around the radiator using a steel can cut in half longitudinally, as a form to shape the phasing section. Also, I've always reversed the center conductor and shield connections rather than leaving the shield interrupted, in the coaxial colinears. I'm surprised it works with the shield.

You've convinced me to make a "Slim Jim" rather than a colinear. I have some 300 ohm twinlead left from my days repairing TVs and installing TV antennas. Under 50W, I'm thinking this should work.

I have always found a Slim Jim to be the best performing antenna. Colinears are not that useful.

you can make a home base uhf collinear 3dbi or 6dbi or 8dbi or 10dbi or 12bdi or dbd. short one,s are more use in hilly terrain the longer the antenna are used for flat terrain.

At 32 min, the very important part, he is cut short. Come on. Very frustrating.

CB is 27MHz. Did you mean GMRS?

477MHz is Australian UHF CB. They also have conventional 27Meg CB .
