All:
I'm looking for mix 75 cores to build a common mode choke similar to the
one Paul, W1VLF shows in this video.
https://www.youtube.com/watch?v=dcXq6u64HXg
The plots show the choke to be very effective on the 2200 and 630 meter
bands as well as 160 and 80 which is what I'm looking to use on my
receive loop.
Not sure what the inside diameter of the cores are that Paul uses, but
they are large enough to get 25 turns of RG-178 around them.
Any suggestions would be greatly appreciated.
