 During 7 months, using QRP and QRPp power (1 watt in 88 QSO, 2,5 watt in 100 QSO, 3 watt in 19 QSO and 5 watt in116 QSO) i was able to connect these countries:

3V Tunisia, 3Z and OZ Denmark, 4O Montenegro, 4X and 4Z Israel, 5B and P3 Cyprus, 9A Croatia, AA and K and W U.S.A., AM and AO and EA Spain, CR3 Azores Islands, D Germany, E7 Bosnia, EA8 Canary Islands, EA6 Balearic Islands, ES Estonia, EU EW Belarus, F France, G and M England, GI Northern Ireland, GM Scotland, HA and HG Hungary, I Italy, IS0 Sardinia Island, SV Greece, KP Virgin Islands, LA Norway, LY Lithuania, LZ Bulgary, OH Finland, OK Czech Republic, OM Slovak Republik, ON Belgium, OY Faer Oer Islands, PA Nederlands, UA R Russia, UA9 Asiatic Russia, SM Sweden, SP Poland, US Ucraina, YL Latvia, YO Romania, YU and YT Serbia, Z3 Macedonia.

So we can say that i had good results, considering that it is a short and stealth antenna.
