[RFI] Rfi help

RG-214 has two shields.  The inner shield is made of silver-plated copper wires and the outer shield is made of tinned copper wires.  Total diameter is nominally .420 inches as opposed to the .405 inches of RG-8 and RG-213.  RG-213 is what would have been named RG-8D (IIRC) and RG-214 is what would have been RG-9C.  Difference is primarily that the "new" stuff has non-contaminating outer Jacket.  Attenuation is virtually identical to RG-8 but maybe a smidge higher at upper frequency range ( again, IIRC).
