The velocity of propagation (v.p.) in each branch of the feed harness
won't affect the relative field radiation pattern of such an antenna
array as long as the same electrical lengths of coax are used between
the power divider outputs and the feedpoint of each element of the
array.

The v.p. of the main transmission line from the tx to the input of of
the antenna power divider in this scenario is irrelevant.
