I built a free-standing 11 meter halfwave dipole. I built it out of an os239 fitting, 1 inch PVC conduit T, some 1 inch to 3/4 inch bushings, some 8 inch nipples (insert joke here), and some 10 foot long 1/2 inch metal conduit. It works great and the SWR's are flatlined. Next to nothing 1.00 to 1.05 on CH20. Here are some pics.
