Default Coax Choke For Receiving Antenna ?

And remember on the ferrites- if they are big enough, you can make
multiple

passes through them- the reactance goes up as the square of the number
of
turns- saves on ferrites.

Hi Dale - I've done this with standard electrical cords (like zipcord),
but that's much smaller stuff and works OK with little snap-on types of
ferrites. Your comment suggests that one would benefit from one of
those great big toroids about 4 to 6 inches across, threading the coax
through it many times - is that right? If so, is it best to wind it
tightly, or does that risk messing up the construction of the coax?

Thanks,
Bruce Jensen


Scarmble winding will be as good as a neat winiding.
