Others will have more recent and more practical comment, but I'd say
it would probably be OK enough.
Digital TV does a marvellous job of making old dead antennae look
almost respectable.
The antenna requirements are modest and a fairly savage VSWR or less
than optimum gain is probably going to be more acceptable than in most
cases.

Conductor diameter can affect impedance when in proximity to other
conductors (this is used for matching in some designs) but the
relative closeness of sizes in your case should be OK enough.

Skin effect has signal on outside of the bundle. Good contact between
twisted together wires MAY help but I'd guess they could almost be
mutually insulated and still be OK.


YMMV :-)
