With an OCF dipole, does it matter which leg, short or long, is connected to which side of the 4:1 balun, hot(coax center) or shield? How can you tell which is which, the balun is not marked. Thank you.

    $\begingroup$ What kind of 4:1 balun is it? Does it have two cores? $\endgroup$ Feb 22, 2020 at 18:10
  • $\begingroup$ I don’t know. It’s a Radio Works balun and completely sealed. About 3” Dia and 4” tall. $\endgroup$

  • $\begingroup$ I saw your post and wonder what your experience has been with the OFCD as I have the same question about which wire goes where but seems it does not matter. Any more thoughts about this? Thanks Steve $\endgroup$ Oct 25, 2021 at 13:42

It doesn't matter. If you change the connection of the OCF dipole nothing will change from the current and voltage flow or distribution points of view.



The only difference will be the RF phase. A "balun" is a transformer that goes between balanced and unbalanced sources and sinks of energy.

Unless you are trying to use two dipoles as an array, the phase doesn't matter.
