John, I converted a set of these using DB Products write up and went by the drawing to the letter except I could not get the long loops. The results was miserable the desense is measured at about 24 DB after carefull alignment. Have you gotten a set to work in the past by using the info from DB products? If you have gotten these to work then what's different? I know the loops but the tech at DB products said it should work with the loops that I have. 73 AC0Y... [EMAIL PROTECTED]
