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

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.
