I need to feed a printed dipole antenna at 600 Mhz from a coax. cable. I plan to connect the input of the balun to the center conductor of the cable and the other input arm of the balun to the cable outer conductor, then the two balun outputs (180 degree phase delta) go to the two printed dipole arms. This prevents the cable from being part of the antenna, I think.
I need a short balun, (I've made a slotted 1/4 wave coax. line balun- that's too long for this), hence I plan to purchase one from MaCom (TP-103 part number) or Minicircuits (
I see alot of different transformer types (shown below from MiniCircuits website) and wonder if going from coaxial cable to the dipole arms must be done with item A only, or can other options be used?
Has anyone had experience doing this, and what the pitfalls may be?
Thanks, (sorry, long question)
