I have included a picture showing the SWR and Theta sweep for this antenna from 6mhz to 30mhz, which was made with an AIM4170C analyzer. This antenna has been hung and tuned, and tested, and is ready for you to suspend from 3 trees, or 3 PVC pipes even, and add your own coax. If you are looking at this, you are probably a ham, therefore, check my QRZ page for some diagrams and other info.
I have worked most of the world on this little setup, with the longest being Kenya at about 9,700 miles, using 40 watts. I have been asked'why dont I sell these? The balun works excellent with alternate loops wires also.. 2m = 7 feet 10m = 35 feet 20m = 64 feet 40m = 127 feet 80m = 250 feet 160m = 508 feet This listing includes the loop wire for a 40m installation.
