Well made an W2DU CANNOT be used in the same sentence! I have had MANY problems with them. The failure was the solder connections on the lugs that connect the coax to the studs/eyes. The ends of the

Interesting -- I'd assumed Rich was referring to the W2DU bead choke type. I know they have some reported deficiencies at low frequency due to uneven heat distribution along the string of beads, but

Jim, A W2DU balun is a "type" of balun which relies on well-established principals. It's absurd to indicate that all W2DU balauns are not made well. You had a bad experience from *one* manufacturer

Rich, There are a number of good commercial options. The ones that I would recommend are the Cal-Av Labs series of "choke" or "current" ferrite bead baluns: http://www.cal-av.com/ These baluns appear

I know we discussed this before, but, I have built several of the W1JR type baluns. I have 6 in various stages of construction. I was never satisfied with the enclosure for dipoles. Didn't matter on

Got lots of loose beads in a drawer from a blown-up W2DU. Me too! A friend of mine blew one up on a 2 element 40 meter beam. Running 1000 watts. 73 Jim W7RY *The problem is not the W2DU concept, but

Indeed. I have had very bad experiences with commercially available W2DU baluns for around $20 or so. All kinds of problems ranging from broken solder connection inside the pvc tube, broken beads, to

I have used W2DU - HF3 - 9KW baluns from ComtekSystems for my 2 el 10-15-20m QUAD for each band. Using ACOM 2000A at 1KW+ with up to 2:1 SWR with no problems and I am very happy with them. Have used

baluns. I do the same. At least at CW/SSB duty cycles, they have held up very well at ~ 1300 watts on 80m. I'm not 100 percent sure there's enough inductance for 160 meters. For those who don't want

I got a bunch of baluns from Force 12 and have had no problems with them. I believe these are of the same type, ie ferrite beads around coax. __________________________________________________ Do You
