And your lack of knowledge is just as bad. Gordon is several hundred miles from the games. You might not have noticed but 70cM doesn't go that far and if the games get interfearance from satellite downlinks then there is nothing we can do about it.

YES - SEVEN HUNDRED AND TWENTY ARISS contacts were completed before ours at Flabob last week. That is 720 groups of students learning more about their respective countries' space programs. That is thousands of classroom hours learning more about space and amateur radio. That is 720 audiences anxiously hearing - at first - no response from the ISS. But then, upon the second or third attempt to contact via amateur radio - a palpable "feeling of awe" from all in attendance when an astronaut first replies. That is 720 audiences wildly applauding after the completion of their contacts. There are about three entities who can schedule radio time with the ISS: the various space programs involved, the various departments of defense involved, and AMATEUR RADIO via these ARISS contacts. There is not a single student nor audience member nor amateur radio volunteer who thinks anything less of their contacts with the ISS - simple because "it has happened many times before." I have 211 attendees who are extremely proud to have been "Number 721" last week. So, to the person who wrote, " ... Too bad its happened many times before ... " - Either you are totally unaware of how wonderful these projects are for all involved, or have never been involved first-hand in such a once-in-a-lifetime experience. I cannot think of any other reason one would make such an ignorant comment.

Yanko, I appreciate you plugging the venerable (aka "old") Egg2 design, and while I still consider it a really good LEO omni antenna, it is with limitations. With today's crop of LEO satellites, none are as strong as the ones available when I first designed and built that model--specifically UO-14 and FO-20 as prime examples of an earlier era's "easy sats." For newbies to the birds, especially if you are starting from scratch, Bob's (WB4APR) suggestion to use a 1/4 wave vertical for 70 cm downlink is a good first antenna--simple and effective. That antenna will give you coverage at high elevations--above 30 degrees, but that means your pass times will be short and your range is narrow (in distance). The Egg2 was designed for exactly the opposite, max gain at low elevations, where most people struggled to hear anything (I know I did!). If you want to work LEO's today (what choice do you have right now?), don't consider an omni without a good preamp (NF < 1 dB). Else, you will become frustrated and lose interest in an exciting hobby. For the price of a good preamp, you could consider a small beam (such as Kent's "cheap yagi" and a TV rotor. Trust me, you'll be happier trying to work AO-27, VO-52, SO-50, ISS, etc. 73, Jerry, K5OE --------------------------------------------------------------- Original message: Hello Carlos, You can try to search for a eggbeater antenna like this one http://victrolla.homeip.net/wo5s/junkpile/432/eggbeater2.pdf Thanks Yanko, NX9G ----- Original Message ----- From: "Carlos Poinho" <cu3ftcarlos(a)gmail.com> To: AMSAT-BB(a)amsat.org Sent: Tuesday, April 24, 2012 4:00:26 PM Subject: [amsat-bb] satellite antenna hello all any one have a good idea for a omni directional antenna for the birds?
