One on 2m, one for 70cm, at right angles to each other, with \nan HB9ABX-design diplexer for the two. I use this handheld with my \nKenwood TH-F7E HT and get into AO-51, SO-50 and AO-27 without any real \ndifficult. Total time for construction about an hour ;-)\n\nIf you've got an antenna analyser or even just a good SWR meter, it will \nhelp a lot with getting the 2m part right. I didn't bother tuning the \ndiplexer much for 70cm because the MFJ-259 antenna analyser I was using \ndidn't cover UHF - so I just woke up a 70cm repeater on the other side \nof town and tuned until I could hear it best.\n\nI find it hard to get into AO-51 when it's busy and people are hammering \nit with huge stacked arrays of antennas. When it's in QRP mode I get in \nno bother at all, with good reports from all over Europe. Not bad for \nan aerial build out of a bit of scrap wood, some brazing rods and a few \nfeet of hydraulic pipe ;-)\n\nGordon\n", "attachments": [] }
