    "content": "Thanks for the information on the Smiley antenna.  So if it is fully extended on 2m it will be a quarter wave, which would be 3/4 wave on 70cm.  How well would that receive the satellites when fully extended.  It looks to be the same length as the Nagoya I have been trying, wonder if it works better.\n\n\n\nThe Nagoya is supposed to be a 5/8 wave on UHF but I really couldn't hear the satellites with it.  Is there a problem with a 5/8 wave antenna for satellite reception?  Or maybe I just got a bad one.\n\n\nI see MFJ has a telescoping 1/2 wave antenna for 2m.  That would be a 3/2 wave on 70cm.  How well would it receive on that band?\n\n\n\n73 John AF5CC\n\n\nSent using {0}\n\n\n\n\n\n\n\n\n---- On Sun, 21 Apr 2024 20:25:34 -0500 Thomas Schuessler <[email protected]> wrote ---\n\n\n\n\n\nA single whip is obviously a compromise.  The Smiley is a tri-band, but with specific whip extensions for specific bands.  The 70 CM and the 2M lengths are different so there will be a compromise on the band that is not the band the antenna is set up for.  I would probably have to make a decision as to whether to set this type of antenna for the RX band or the TX band.  Resonance on TX means more power transferred to the antenna.  Resonance on the RX band means better reception at the expense of RF out (Radio power foldback if SWR is too high).\n\n\n\nClint, you are missing a very good, easy to build dual band Yagi by Kent Britain, WA5VJB.  Search \"WA5VJB cheap Yagi\".\n\n\n\n73, Tom, N5HYP\n\n\n\n\nOn Sunday, April 21, 2024 at 07:08:31 PM CDT, Clint Bradford via AMSAT-BB <mailto:[email protected]> wrote:\n\n\n\n\n\nSmiley 270 - out-performs the Diamond SRh-320a ... at half the price.
