[. . . ] BARKER & WILLIAMSON 603 CIDCO ROAD COCOA, FL 32926 321-639-1510 MODEL AT-110 ANTENNA 80, 40, 20, 15 and 10 Meter Bands Power Rating: 1000W PEP, 500W Output Length: 110 Feet The Barker & Willamson Model AT-110 is a short dipole for the 80, 40, 20, 15 and 10 meter amateur bands. The 80 and 40 meter bands have a seperate trap (40 meters) which will give maximum efficiency and still be a short antenna for small lots and limited space. [. . . ] Where practical, antenna conductors shall be installed so as to not cross under electric light or power conductors. It is imperative to follow the instructions step by step, in the order shown, to achieve satisfactory results with your antenna. (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). 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. After the desired frequency is achieved, make permanent attachment for these segments as shown in figure 2, trimming off excess wire.
