Shakespeare 4104

This antenna was designed to cover 23 ch only. The elements are shakespeare 10-3 style fiberglass mobile whips the lengths are correct due to the small dia wire in the whips. If i remember the thing used some type of coax matching section to feed it. After you changed the whips around and got low swr around ch 1 your on the right path . as others have commented you must have the lengths in decreasing order starting with the reflector. If you need to have low swr higher in the band try shortening the driven elements only an inch at a time. Have a couple of old fg whips you may want to replace the driven element whips and try tuning those first, Keep in mind this antenna is only going to cover a limited portion of the band. I played with several of these and they are touchy. They even made a stacked pair.

Good luck RCB[PHP][/PHP]
