Contact Jim there to purchase one. Maybe Marv's book store has it. Ferrire beads or Baluns (BALanced/UNbalanced) (rymes with Alan) matches a balanced dipole antenna to an unbalanced coaxial cable. Ferrite beads are one type of balun. Install the beads over the coax at the antenna end just short of the first removed insulation. Use three beads spaced about 1/4" apart and using silicone RTV and shrink lock them in place there. I have read and reread Jim's pamphlet as it is full of good stuff for your aircraft radio/antenna installation. There are designs for home made antennas, splitters and baluns also. I have many extra beads I could sell an my cost. Walter Dodson wdodson@bak.rr.com
