I had a 20 meter dipole about 65 feet over the house. The antenna had
a flat swr on 14.336 where I often hang out. On the low end, it was too high to use below 14.020 so I only lost use of a portion of the extra portion without a tuner. (flat defined as according to the 706 MKII internal meter.) This evening I cut a pair of wires 4.5 feet long each. I added them to the 20 meter connection center connection at the coax and let them hang about 8 inches below the 20 meter wire. I also changed coax from cable-tv coax to RG-8 foam. I rearanged the antenna just a little with also allowed for an additional 10 feet of height. I now have a 20/6 meter dipole at about 75 feet high with the legs pointed almost exactly east and west.. 20 meters is now flat at 14.030 and the top edge of the band is only 1.3:1. The 6 meter dipole turned out to be flat on 50.1. So far, I am quite happy with the antenna. I am having a 6 meter QSO as I write this. (The other party loves to talk and hasn't unkeyed for at least 5 full minutes.) Based on our current conversation, It appears that my next antenna will be a loop. Comments are welcome, Thank you, -- 73 for now Buck N4PGW |
