A rotating quad for 80 meters are you crazy? well i did it and it worked well. now i’m not saying that i think anyone else be as nuts as me but it seemed to fun be idea at the time. i remember calling into a local 80 meter net on 3.755 mhz asking for a front to back check – they thought i was bananas.
200 ft of wire in each element with 25 foot tuning stubs, 40 ft front to back spacing, top of diamond at 135 ft, 85 ft boom as main support structure, front to back 25 db, front to side 40 db, reflector tuned to 3.6 mhz, operated as a reflector on phone and as a director on cw.
The 2 element QUAD for 80 meters with 40-ft front to back spacing and the top of the diamond at 117-feet. Note: Because the tower is telescopic the top height may vary from project to project.
The photo below, shows the quad on it’s way up to 125 ft. Note the wires drooping with the tower about half way up. The end elements at each end will be pulled up with the antenna wire when it reaches full height..
