    Is some types of coax made with stranded wire?

    yes.
    look for coaxial cables labeled "ultra flex" or just "flex". they will have a stranded center conductor.

    for example, LMR400 and LMR240 have a solid center conductor, and their "UF" counterparts have a stranded center conductor.

    My reason for asking is ,I was in a class for electrical and the instructor said stranded Carrie's more current than solid wire.

    if it was in context of "electrical" as in home wiring , power distribution, ect... He would be incorrect. 10 ga is 10 ga , whether solid or stranded and has the same amp rating.

    @ RF the added surface area in stranded does change the capability.

    Solid core conductor coax is slightly better spec wise but the trade off is lesser strength and durability compared to stranded.

    Check specs on coax manufacturers like Times microwave that make both types to see the differences.

    In the real world, you'll never notice.

    Solid coax is ideal to use for running thru walls where you might need several permanent bends. Repeated bends can weaken if not damage the center conductor.

    I use RG213 for the balance of a rigid like cable but still has a stranded center core for some moderate flexibility. I also use RG8 for flexible jumpers because RG213 is a bit stiff at short pieces.

    I use 213 for my beam for flexibility over the rotator, then 9913 from there to the shack.
