When I first returned to the sats I homebrewed a couple and they worked fine. But even better is a Moxin style which provides gain and circular polarization. See Larry Cebik\"s article in August 2001 QST. I built these and they worked great for the LEOs.\nGreat for portable too, as are omnidirectional.\nKevin/W3DAD\n\nOn Mon, Jan 25, 2016 at 6:38 AM, Greg <[email protected]> wrote:\n\n> Fred,\n>\n> In addition to Kevin’s idea, you might want to consider some home-brew \n> “eggbeaters.” When I first started on the LEO’s, they worked fine to \n> get into the birds, including the ISS.
