"Jack Twilley" wrote in message ... I tuned up on the dummy load, then switched over to the real antenna and checked the SWR. Here's the results: Frequency Dummy Antenna 3.750 1:1 infinity 7.150 1:1 2.5:1 14.175 1.05:1 3:1 21.225 1.1:1 3:1 28.850 1:1 1.9:1 Jack, I don'r have any experience with the noise bridge, but based on the SWR readings, I would do the following: Since you have no 80m radiator, ignore that band for now. Measure the SWR at 7.0 and 7.3+ to determine whether the 40m wire is too long or too short, and trim to size. Repeat at 14.0 and 14.3+, and 28.0 and 28.5(?), assuming you want the most used part of 10m. I guess you are useing the 40m radiator on 15. Tam/WB2TT |
