I'VE HAD GREAT LUCK WITH ONE FEED, RG-8, AND .2" LUCITE SPREADERS THAT KEEP
THE WIRES AT LEAST 3" APART. THE NEAR VERTICLAL LOOKS THE BUSIEST, SINCE
ALL OF THE 1ST ELEMENT DROPS COME OFF THE COAX SHIELD AT THE SAME POINT,
WHICH IS A DRILLED EQUALATERAL TRIANGLE ABOUT 6"/SIDE. 4 HOLES FOR THE
FIRST ELEMENTS HEADING DOWN, THEN 4 MORE FACING OUT FOR THE PHASING LINES
TO WHERE EACH 2ND ELEMENT DROPS, -EACH FROM ANOTHER LUCITE SPREADER. THERE
IS SOME INTERACTION BETWEEN THE 15 & 40M ANTS, SO MAYBE I'LL DROP 15M AND
REPLACE IT WITH 12M. (WIMPS IS A MOTIVATION FOR THAT MOVE, TOO!) I HAVEN'T
TRIED OPEN LINE SINCE THE FEEDPOINT IMPEDANCE IS BELOW 100 OHMS RATHER THAN
ABOVE IT. JUST TO KEEP MY COAX CLEAN I USE A BEAD BALUN. THE FEED FOLLOWS
THE SUPPORT ROPE ABOUT 25 FEET BACK TO THE SUPPORTING TREE TOP, THEN DOWN
AT A FAIRLY STEEP ANGLE TO GROUND LEVEL, THEN TO THE HOUSE FOR A TOTAL
DISTANCE OF ABOUT 120'. THE ANT IS MADE OF HOME DEPOT #14 THHN STRANDED. I
FOUND THAT THE USUAL DIMENSIONS WERE A COUPLE OF PERCENT LONG, PROBABLY CUZ
OF INSULATION EFFECTS. I USE 12 TO 16 OZ. OF LEAD AT THE END OF EACH ELEMENT
DROP TO KEEP THE WIND-WHIP UNDER CONTROL. I MAY TIE EVERYTHING IN POSITION
WITH LIGHT MONOFILIMENT LINE TO PROVIDE FURTHER STABILITY.
THAT'S ABOUT IT. SIMPLE, CHEAP AND WORKS LIKE A CHAMP. 72, =S=
