BM & David,

Using the Coax Cable as a Counterpoise under the
Inverted "L" Antenna as shown.
{ Counterpoise = A Single Ground Reflector / Radial }

Reversing the Lay-Out of the Inverted "L" Antenna allows
the Coax Cable to be placed on/in the Ground under the
Horizontal Antenna Element and have it act as a single
Ground Radial.
