Impressive - S7 Stations get lifted to S9 / S9+10, bairly audible stations seem to get an SNR lift also... and it was just a quick desktop-check. Let´s see what happens during tropo (it´s been a while...) or even sporadic-e some time soon...

(noise and cable leaks are lifted also... but in terms of noise, it´s fine, as long as SNR rises...)

Great, looking good Tony. Are you going to install it up on your mast? Will be even more impressive there :)

Yepp, I need to minimize signal loss .For testing purposes I simply used two cables, 10m each. This
isn´t really state of the art, even though 10m isn´t that long. :D
