Plans for the antenna can be found here: https://www.hamuniverse.com/wonderbar.html
I used #14 insulated common household wiring for the coil and #16 hook-up wire for the "bowtie" part and the 2-turn coupling loop. The bowtie shape I made using four 4ft. fibreglass driveway markers from a nearby agricultural supply store attached with u-bolts to a plywood base.
I found that I needed the entire length of the centre loading coil (no need for a tap) and I found that horizontal part of the bowtie needed to be 51" long, not 48" as shown on the web page above.
