Construction Details Drill a PVC Cap to accept SO-239 (7/8") and 4ea  #6 screws, lock washers and nuts. Make sure to center the SO-239 in the hole before drilling the 4 screw holes. Lock washers go under the nuts.  3 screws are 1/2" and the other is 1". Cut off the head of a 1" #6  brass screw and solder it in the center post of SO-239 Cut antenna wires to length plus a little Fit one end of each wire with solder lugs Fit the other with the egg insulators and parachute cord or other non conductive rope which serves as guy ropes on the ends of the 4 elements. Two guy ropes should be at least 7.5' long for the 38 foot antenna wires and 20.5' long for the 25 foot antenna wires. Locate the 4 Plexiglass pieces and drill 3/8" holes on each end. Slip the guy rope through one hole and tie it to the other. See picture on last page if you have trouble visualizing this... These pieces allow you to pull the plexiglass piece up the guy to shorten it and adjust the tension of each guy. The total length of each element... wire and guy... is about 45 feet. Next
