Maybe that's the problem. They'd rather double the radios and put one vertical, and the other horizontal (or put 3 in there with 802.11n)...\n\nGreg KO6TH\n\n\n> From: [email protected]\n> To: [email protected]\n> Date: Sat, 16 May 2009 14:48:56 -0700\n> Subject: [amsat-bb] Re: Gain VS Bandwidth at 2.4GHZ\n> \n> Greg,\n> \n> You got me thinking about going circular!
