Stella DB answered your questions, and YES it will suit your purpose of trying to prevent CMC on your coax and allow you to get accurate measurements of your antenna system.

Line isolater, RF choke, 1:1 current balun all do about the same.

Exception to a TRUE current balun which forces equal currents onto a balanced antenna using an unbalanced feed line.

So Stella you are using coax, unbalanced feedline, and a vertical antenna, unbalanced antenna,so either the RF choke or Line isolator will suit your needs where a 1:1 current Balun will not.
