[. . . ] BARKER & WILLIAMSON 603 CIDCO ROAD COCOA, FL 32926 321-639-1510 MODEL AS-80 ANTENNA 80, 40 and 20 Meter Bands Power Rating: 1000W PEP, 500W Output Length: 78 Feet The Barker & Willamson Model AS-80 is a short dipole for the 80, 40, and 20 meter amateur bands. Each band has a separate trap (20 and 40 meters) which will give maximum efficiency and still be a short antenna for small lots and limited space. [. . . ] (2) Remember that throughout the assembly procedure, wire lengths are always to be symmetrical on both sides of the antenna. The wires must be cut approximately 2 - 3 feet longer than the dimensions shown in figure 1. Here are the lengths that you should cut (including the 2 - 3 ft extra). Cut two wires 21', two wires 15', and two wires 11' 6". Remember, you can always trim the wire shorter after tuning, but once cut too short . (4) Attach one end of the wire segments in the permanent manner shown in figure 2, working out from the center conductor. Allow roughly 6 to 8" of wire through the eyebolt before starting your wrap. (5) Now assemble the sections of the antenna together paying attention to figures 1 and 3. The wire segment lengths shown are your starting point for tuning the antenna. This will leave each wire segment with one end permanently soldered, and the other end temporarily connected for adjustment. If the resonant frequency is low, shorten the 17' 11" segments. After the desired frequency is achieved, make permanent attachment for these segments as shown in figure 2, trimming off excess wire.
