Gents:
My shunt wire consists of two parallel #14 wires separated from each other
by 18 inches and held off the tower face two feet. I use several T's
constructed of 3/4 inch PVC tubing as the support elements for these wires up
the tower face. Perhaps this arrangement is what helps my shunt-fed tower
exhibit such a broad BW on 160M. If anyone wishes a photo, let me know.
