And you mention height? This means that it begins at 'X' inches from the reflector? And the coax just feeds up to where it starts?
Yes. You can feed it in from any direction. Build the helix as normal, then add the match.
Height is defined as the distance from the reflector to the bottom most part of the stub.
The coaxial cable feeds directly into the stub, yes.
