CONDUCTIVE MAST GUIDES THE VERTICAL SIDE OF TWO IDENTICAL RIGHT
TRIANGULARSHAPED WIRE LOOPS TO FORM A COMMON OR SHARED APEX.  EACH LOOP IS
DRAPED IN A SYMMETRICAL MANNER ABOUT THE MAST, ORIENTED IN A COMMON
VERTICAL PLANE, AND HELD IN TENSION BY AN ANCHOR FORMING A HORIZONTAL BASE
THAT IS SPACED A FEW INCHES ABOVE THE GROUND.  EACH LOOP IS CONSTRUCTED AS
AN ENDLESS WIRE LOOP THAT IS ROUTED THROUGH A GROUP OF FERRITE CORES
FORMING A CURRENT TRANSFORMER ACTING AS A COUPLING LINK.  THE COUPLING LINK
IS POSITIONED AT A DISTANCE FROM THE MAST AND IS CONNECTED SO THAT THE
ANCHOR SIDE OF THE TRANSFORMER IS CONNECTED TO THE CENTER COAX CONDUCTOR OF
A LOOP FEED LINE.  THE LOOP FEED LINE FROM LOOP 1 IS CONNECTED TO A
REFERENCE LINE.  THE OPPOSITE END OF THE REFERENCE LINE CONNECTS TO AN
INPUT PORT OF A COMBINER AMPLIFIER THAT WILL BE DESCRIBED LATER IN THIS
ARTICLE.  THE LOOP 2 COUPLING LINK IS POSITIONED AT A DISTANCE FROM THE
MAST AND IS CONNECTED SO THAT THE ANCHOR SIDE OF THE TRANSFORMER IS
CONNECTED TO THE CENTER COAX CONDUCTOR OF A LOOP FEED LINE.  THE OPPOSITE
END OF THE FEED LINE IS CONNECTED TO A DELAY LINE.  THE OPPOSITE END OF THE
