Thanks Mark. I knew what I was trying to say but something got lost between my brain and the keyboard. I wasn't sure if you knew some secret to the dipole configuration. My father was a Ham operator and designed antennas. He would often come up with unique and strange setups. I should have paid better attention. Thanks for the clarification
