In the past, I have used a 2-element 10 meter yagi. Unfortunately, a G5RV is a mediocre antenna at best for bands other than 20 meters for which it was actually designed. Glen, K9STH Website: http://k9sth.com --- On Fri, 9/11/09, John Geiger wrote: What is the minimal antenna you can use o

Hello John, I use a dipole monobanda of wire for 40 m when the satellite is closest to my station. When satellites moves away from my station, I use a 3-element yagi for 10, 15 and 20m. Unfortunately until now I could not work stations out of Brazil in mode A, considered that Brazil is a count

John. I dont know about the G5RV...but at the St. Cloud House in Clear Lake I can hear it with a homemade J Pole, two dipoles 90 degrees to each other and a converted CB whip... The RX is a very well maintained Heath SB 300 and a Radio Shack 10 meter box At Santa Fe (our "gentlemans farm") n
