Who can tell me the good supplier for type 31 1.5 inch diameter cores to
wrap RG142 around?

Thanks to new tariffs on these materials, which are manufactured in Fair-Rite's factories in China, prices have doubled since June, when I paid about $3.25 each for 100.

BTW -- RG400 is a far better choice, because the center is silver-coated stranded copper. Even with that center, the smallest one time bend radius spec I have seen for it is one inch. RG142 has a SOLID silver-coated steel center, and the minimum bend radius is significantly greater.
