My guesstimate on the #antenna radiation pattern for my antenna built from an #umbrella (crudely illustrated) -- pointing it in various directions at a weak repeater, and listening to the signal while people were talking this morning. #hamradio #hamtenna

@tsherrygeo Neat. Do another that shows it supporting an antenna ... I assume you use pretty thin wire.
