    "content": "Yeah, it does get a bit complex with the phasing stubs and impedance\ntransformers, the need for coax of an odd impedance (70 ohms which doesn't\nexist, so 75 ohms used as a compromise), etc.\n\nThat's why I advocated using a 2-port power divider, a device which\nphysically acts as the impedance transformer needed to connect two 50 ohm\nantennas in parallel and remain at 50 ohms to the radio connection. And if\nthe \"mechanical method\" of getting the quarter wave offset between elements\nis used, then no need to get coax feeders of different lengths by exactly a\nquarter-wave after adjusting for velocity factor. Just two pieces of 50 ohm\ncoax of exactly the same length, which can be easily verified with\nrelatively simple test equipment, namely a dual-channel oscilloscope with\nx-y plotting mode.\n\nOn Fri, Feb 10, 2017 at 8:28 PM, Kevin M via AMSAT-BB <[email protected]>\nwrote:\n\n> You may find this page very useful...
