Hi Group,

In the process of fab'ing a off-center dipole. The short end is 40 feet and
the long end is 80 feet. At the feed point I have a 4:1 balun. The balun I
purchased new, I believe it has w2un on the side of it. I don't have it here
at the computer.

The question is what side of the 4:1 should I feed the long end, or does it
matter?

Why do you believe you need a 4:1 balun?
(The fritzel Off-center feed dipole uses a 6:1)
Have you measured the feedpoint?
(It's so much better to work with facts rather than myth.)

As to your "side" question, what "side" does any transformer use?

DOESN'T MATTER

Hello Paul,

If it is a true balun, it does not matter.
However out of proper experience, I would recommend using an additional 1:1
current balun between your (voltage?) balun and the coax.

Although a 6:1 balun offers more possibilities, I also had to design an
off-center fed dipole around a 4:1 balun I had at hand.
You can find design details he http://salsawaves.com/antennas/windom.html
