Hello, Last weekend (CQ 160m CW Contest), I rise a 5/8 vertical antenna with meteo baloon (Total length 100m) with 15 radials of ë/4. I believe that I didnt match it correctly. Can you tell me the best way of matching this antenna??? Do not forget that next month we have the CQ160mSSB Contest. Many thank in advance George Vlahopoulos, SV1RP
