I made a home brew antenna today. I built a 1/4-wave ground plane with 6 ground plane elements today. The SWR is a tad high at the higher repeater channels/frequencies (467MHz). The 462MHz channels/frequencies run a low SWR. I will try making the angle on the ground plane elements a bit steeper first. Then I will try trimming the element lengths, bit by bit. This will be one of my "go box" antennas. I may try a commercial made antenna with a ground plane kit I bought from here. I broke one of the ground plane elements, so will replace them with 12AWG copper wire. The quagi long-beam I built to use for reaching a distant repeater had very high SWR. It was scaled from a 440MHz antenna design. I need to rework the quad loops on it to match it. Another project I want to build is a cubical quad "go box" antenna. So many projects, so little time... Trying to fix up our home to sell at the same time.
