Most people thought a TX loop would not radiate out of a backyard. That was proven very wrong many years ago. The calculations say a TX loop is a terrible antenna, but it does radiate very well. Might it work on the 9kc band? Maybe. Dex W4DEX used a TX loop for his VLF experiment many years ago on 7 or 8kc with very low power. He covered 10km I believe. One never will know until someone builds a proper 9kc TX loop and tests it. Might be a big surprise, might not. We know it will absolutely require a low loss conductor, low loss series resonating caps, and the proper matching transformer. Mike WE0H |
