If so, have you\nconsidered the Lindenblad by Tony, AA2TX?\nhttp://www.arrl.org/qst/2007/08/monteiro.pdf\n\nIf you're building either antenna specifically for VO-52, you might\nconsider making it LHCP, which I believe is the polarization of the 2m\nsignal transmitted by Hamsat. (Tony reports that his RHCP design\nnonetheless receives VO-52 well.)\n\nA low noise preamp at the antenna will make a huge difference also at 145 MHz.\n\n73, Bruce \nVE9QRP\n", "attachments": [] }
