Hello Popa

Here still using 8 x EF0211B and I am very satisfied - it has been real winter, we 
have had lots of snow, ice and cold (for 2 months near -30C) ... no SWR problems
I have excellent RX ... and lately have tested also about kW TX pwr  ...  signal is big 
System works fine, it was easy to work FY/DL2NUD and 3A/DL8YHR, or it was
easy to work IT9JRU (2 WL/100w) hi!
