[Amps] RF Chokes

[Will Matney]

Hal,

Yup, they sure can still couple being in a straight line. The coupling is weaker the farther aprat they are, but how much it takes to fully decouple one from another, I don't know. Mounthing the sections at 90 degrees does de-couple them. It works the same as a grid dip meters coil. It has to be parallel to the coil to be any good, not at 90 degrees. Parallel means it's coupled to it and that the flux is cutting through both coils. I've mounted power transformers at right angles if the had to be mounted close together.

Best,

Will
