From the recent tests with G3KKD it looks like my 3el 2m and 5el 70cm beam (or the feeder?) is faulty. I may take it down to see what the issue is. I had plans to replace the hand-rotated beam with big-wheels which have a little gain (3dBD) and do not require turning. I noticed the VSWR was rather high the last few times the yagis were used. Last night, even with just a halo and a run of lossy feeder I did almost as well as with the beam on 2m, so a single big-wheel plus a run of low-loss feeder should see an improvement of 2-4dB over the halo, if not more.
