-G-

A = Antenna {Longwire} Termenation/Connection
C - Coax Cable {Center-Conductor} Connection
G = Ground Coax Cable {Outer-Shield} Connection
.
A-to-G and C-to-G would read as near DC "Shorts"
since they are short pieces of Copper Wire.
- - - Also A-to-C would read as a near DC Short
due to the Series Circuit Path.
.
Inductively [AC & RF ] A-to-G and C-to-G would
each read as Reactance and function as an AC
Parallel Circuit Path.
