A Portable 3-Element 2-M Beam The following beam plan can be found in the ARRL Antenna Handbook and in the April 1993 QST. The beam was designed by, Nathan Loucks, WB0CMT. The boom and mast are made from 3/4 inch PVC plumbers pipe. The three pieces of PVC pipe are held together with a PVC T joint and secured by screws. Elements can be made from brass brazing or hobby rods. (If you can't find a 40-inch rod for the reflector, you can solder wire extentions to obtain the full length.) Drill holes that provide a snug fit to the elements approximately 1/4 inch or so from the boom ends. Epoxy the director and reflector in place after centering them in these holes. A pair of holes spaced 1/4 inch and centerned 16 inches from the reflector hold the two-piece driven element. The short ends of the element halves should extend about 1/4 inch through the boom. Solder the 50-๊ feed line to the driven element. You can trim the driven element to length for opperation in the desired portion of the band.
