While this design "won't cause problems," it also won't do anything
useful. That's because Fair-Rite #61 material makes a lousy choke at HF
because it's not lossy at HF. Study k9yc.com/RFI-Ham.pdf
And let us know wazzup with your new project NOT using RG-142 and the stainless
steel conductor.
The project I'm working on is for legal on 160 and 80M. The
silver-coated, copper coated steel center of RG-142 is fine at VHF and
UHF thanks to skin effect, but the steel causes losses to increase at
lower frequencies as compared to copper or silver coated copper.
Thanks to all for the great advice offered. I've received several great
recommendations for products and sources.
