I was tuning around the radio last night while waiting for Fedora 18 beta to install on the computer and heard 9A9A from Croatia calling loud and clear. He had quite the pileup going and it was interesting listening to him work everyone. A little while later after the pile up cleared away, I called him and managed to get him on the first attempt. First contact with the new antenna and it was a DX from almost 7900 km away! His signal was easily 59+ like he was next door, and I got a 59 back from him.
About 40 minutes later, I heard UT2IJ in the Ukraine calling and working a pileup too. Rather than wait, I responded and managed to work him on the first try too from 9100 km away! His signal was pretty good, a 58 and I got a 57 back.
Looks like the antenna is working pretty well.
