    "content": "Quoting EB3JT - Jordi <[email protected]>:\n\n> \n> AO-07\n> \n> My longest distance:\n> \n> Date:21/11/2006\n> Calls: EB3JT<->AJ9K\n> SMode: AO-7/ Mode-B\n> locators:  JN01UI<->EN53EB\n> Distance ~7114 km.\n> \n> 73 de Jordi\n> EB3JT\n> \n\nI'm very much enjoying this thread and wonder if we could expand the\ndiscussion to include the simplicity or complexity of the antennas used. \n\nWhat's your best LEO DX distance using \na) fixed elevation and an azimuth rotator\nb) omnidirectional antennas?\n\nI request this because I've noticed that a number of beginners to the\nsatellite aspect of our hobby arrive with the conclusion that a full az/el\nsetup is required. No wonder: the ARRL Handbook stipulates this. I was\nfortunate enough to follow the wisdom of this list, which recommends a\nfixed elevation, low-gain beam setup, and have had a good deal of DX fun on\nAO-7 and, especially, FO-29 using that, much simpler, system. \n\nI'm attempting to upgrade to longer beams and az/el rotation (principally\nin preparation for HEO operations), but I'm finding that the increased\nwinter wind-loads and strain on the mast make engineering this affair much\nmore difficult (and costly). Put it another way, my trusty old wooden mast\nbroke when I tried hoisting the new setup, and my new 9 ft. long 2m beam\nkeeps being rotated in elevation by the darn wind. (Living just at the end\nof the Bay of Fundy, the winds can be pretty serious and sustained.) I'm\nenjoying the challenge of it all, mind you, but only because I know I can\ndown-grade to the fixed-elevation setup when I wish. I also discovered that\nmy wife's training in the Canadian Naval Reserves comes in very handy when\na mast needs to be temporarily lashed up.\n\nWith the ground frozen solid until, probably, April, I won't be putting up\na new mast any time soon, so my mind turns to experimentation with\nomnidirectional antennas, especially the Lindenblads described by Tony,\nAA2TX, in the 2006 Symposium collection. These I could get up on the end of\njust about any long piece of wood, and they wouldn't bounce around in the\nwind. Fantastic for Field Day, too, I'd think.\n\nSo overall, I think it would promote the KISS principle if we highlighted\nour exploits with modest equipment, at least on one end of the link.\n\n73, Bruce \nVE9QRP\n",
