[Antennas] MFJ-1796 multiband vertical

Dear Hue and Readers:
 Your comments are helpful to those not as knowledgeable in antenna theory. One of the problems with e-mail is that there is no audible tone inflection. As a consequence, one can read a tone that doesn't exist. I thought you felt my experiences with the antenna were less than helpful and responded accordingly. My apologies for the miscommunication.
