KD7YZ Bob: Not your original question, but most are not aware that the common J-pole is a vertical polarized Zepp. I built a dual-band J-pole for 6m/10m and use a coax relay to switch feed selection for either band. No tuner required for the band segment I desired. Full description at: http://www.kl7uw.com/J-Pole.htm 73, Ed - KL7UW
