I have cut several Van Gordon baluns apart.
They are tri-filer wound with #14 on a 3/4" PVC pipe form about 2.5 to 3"
long.
Pretty simple.
The worst problem that I have had with many balun manufactures, including
the W2DU blaun (both styles, dipole and yagi) is that where the connections
are soldered to the top "eyes" is usually poorly soldered. I've Had several
of the W2DU baluns fail at that point.
In my opinion, if a balun doesn't have wires coming out of the balun
housing, soldered to the internal windings, it's worthless. Too much to go
wrong when you rely on a stainless eye that is through plastic.

> Well the balun checks out as a voltage type and I have been believing it
was a current type. I did the ohm meter check on the coax and it showed a
dc short across the coax. I suppose given the symmetry of an A3S a voltage
type is fine although I really had preferred to put a current type up there.
Anyone ever take one of these apart? How is it constructed? What materials
used? I can't seem to find any information on the web about it. I did use
a solder gun to make the connections to my hook up wires from the lugs under
the eye bolts and no problem yet after being in the air for the past 3
months.
