ZS6BKW and OCF antennas are notorious for RF feedback. What construction method is in use for the OCF Balun I wonder. I use a dula core Balun Designs unit and still at times there is a small amount of RF feedback seen.
I used a ZS6BKW for several weeks and RF was always problematical. Gary On 2 November 2013 14:47, KC6CNN <kc6...@gmail.com> wrote: > The two antennas are a zs6bkw and a OCF dipole.
