    "content": "I agree with Dee, but I'll add my opinion.  The fixed elevation option is a good approach to reduce your costs.\n\nIf you are going to fix the elevation, do *not* use a very high gain antenna with a narrow beam width.  You are better off with a moderate gain antenna (for example, the Elk or 4-7 element vertical or 2x7 circularly polarized) so that you have a wider beam width.\n\n73, Steve N9IP\n-- \nSteve Belter ([email protected])         My Desk: 765-269-8521\nIndiana Dataline Corp                 Billing: 765-269-8502\n427 N 6th Street, Suite C     Wintek Internet: 765-269-8503\nLafayette, IN 47901-2211    Wintek Consulting: 765-269-8504\n\n> -----Original Message-----\n> From: [email protected] [mailto:amsat-bb-\n> [email protected]] On Behalf Of Dee\n> Sent: Thursday, March 24, 2011 2:18 PM\n> To: 'Ted'; [email protected]; [email protected]\n> Subject: [amsat-bb] Re: Antenna discussions\n> \n> The actual fixed elevation on the AZ rotor is determined by the beam width\n> of the yagi antenna used.
