It can be represented as a point within the unity reflection
coefficient circle on a Smith chart...

Seriously, it depends on SO many factors you haven't specified that
it's not realistic to expect a single answer. How high above what
kind of ground? How many turns, spaced how? What diameter is the
helix? Is it stretched in a straight line, or bent? ...
