This is the N4TZE Coaxial Dipole for 6 meters. You can either hang this antenna vertical or horizontal. This one is put up vertically. You are suppose to have at least 6 inches of separation between the coax feeding the antenna and the element, however that did not happen. It still out performs anything that I ever used. The coaxial dipole is constructed from 75 ohm coax and is feed with 75 ohm coax. If I spent time tuning the antenna I would get better than a 1.5:1 SWR. I just put it together and put it up. The center feed point uses a 2 inch PVC plastic coupler that has a SO-239 connector I mounted in it.  This picture is from my notebook where I keep all my designs and projects that I build in.
