With the forthcoming PACC contest (The major Dutch contest) I had one antenna to improve. I considered a OUT or COMET 250B or F vertical antenna. But if you understand how this antenne works it could not outperform any homemade antenna. After some searching on the internet I came to the conclusion that the best way is a autotuner direct under the antenna if you feed it with coax. SO I bought a CG3000 autotuner an connected it to my GP. I first disconnected the 1:9 balun and made the antenna 8,5 Mtr long. Next thing is to put it up again and connect 4 radials to it. But since we have bad weather at the moment I have to wait. Hope this antenna works in the PACC contest as we do could not depend on good propagation these days.
