An old guy around here where I live, used to say you could talk around the world on 10 W, you just need a good antenna, really good coax, and when the propagation is correct, you can talk anywhere. I’m sure you’ve heard it 100 times and I heard it also but the antenna and the coax will work very well with a cheap radio also. I’m glad to see everybody having such good luck with the Sirio antenna.In radio, propagation is everything. However, having a good antenna system, good coax being part of that antenna system, cannot be overstated. The SWR plot on my Sirio is very much like the one sp5it shared. This is the first Sirio that I have owned and thus far I am very pleased. It does very well on AM local in my area. But, I most enjoy working side band. This afternoon I worked SSB for about three hours. The 11 meter propagation was very good. I was able to work two stations in England on 36 and 37 LSB. And worked all across the country as well. It is a good antenna.
