Wayne, RT142 is a triaxial cable that is no longer in the Times Microwave catalog. Since the two shields are insulated from each other, that cable will not perform well where two shields are needed. It is a special-purpose cable that is intended for use with Trompeter and similar triaxial connectors. Moreover, it is not a Mil-Spec cable and is not interchangeable with RG-142 or similar double-shielded cable in which the shields are directly in contact with each other.

I have some cable that I cannot find the true information for. it is labeled as follows: 68999, TIMES MICROWAVE SYSTEMS, RT142 It is not listed, at least not readily seen, on the Times microwave web site. It appears to be a version of RG142. It is tan outer cover Double shielded, high density silvered (or tinned) with insulation between the two shields.. clear solid inner insulation, and stiff solid center conductor. I bought it to use as RG142 for jumpers. It looks virtually the same as some labeled RG142 that came with a Micor UHF duplexer, though less flexible than the RG142 seems to be. I now wonder if it is interchangeabe or not? I have never seen any cable labeled RT instead of RG... Wayne WA2YNE
