I built this antenna and just wanted to share it. As long as you get it 1/4 wavelength off the ground it works very very well. A friend and club member designed it and he really knows antennas. He should, he has a doctorate in electronic engineering and worked for Motorola as lead designer for antenna design. Check out the plans and have fun with it. I'm very pleased with mine especially on 20m and 40m. http://www.w4wta.com/Off_Center_End_Fed_Dipole.htm
