- 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
