[Lowfer] Need a VLF-LF Coax Choke

[Steve Ratzlaff]

There's an article here, scroll down near the bottom to the "Is your Coax 
Leadin an Antenna" link and download it. It tells you everything needed to 
build a common mode choke. Use small gauge coax like RG174 or the Teflon 
version and wind as many turns as possible on the designated toroid core.

Works great, I've built many of them over the years.
