4:1 Balun question

Question

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.

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.

Phase

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.
