These antennas are very poor\nperformers for working either SO-50 or AO-27. Even under an ideal\npass, using these antennas will likely result in many missed calls.\nWe all know \"it can be done...\" So can running a dogsled race with\nChihuahuas.\n\nHere's my case, which has been experienced time after time, on the\ncurrent FM birds:\n\n1. New station decides to \"give sats a try.\" (Excellent - we should\nencourage and provide proper guidance)\n2. Station looks in drawer and finds an extended whip or buys one\nbased on recommendation from website or article\n3. Station gets on a pass, hears a break in the noise and some partial\ncalls, so he gives his call sign\n4. If the new station was lucky enough to capture the bird, likely\nother stations will \"pounce\" on the new guy and perhaps call\nincessantly\n5. Perhaps the new station will hear the bird again for a minute,\nthinking it is clear, and gives their call sign\n6. Repeat step 4-5; continue until LOS (many fewer good contacts are made)\n\nWhen we had AO-51, reception on an extended whip was more viable. Now\nwith AO-27 and SO-50, these \"extended\" rubber ducks have become much\nless viable options. Often the stations on a whip do not take into\naccount their \"handicap\" and try to make contacts even though they are\nnot hearing the bird.\n\nIt’s time to retire these extended whips as a recommendation since\nthere are both inexpensive commercially-available gain antennas and\nmany good home-brew designs.\n\n73\nClayton\nW5PFG\n\n", "attachments": [] }
