User manual BARKER & WILLIAMSON AS-20 TRAP ANTENNA

[. . . ] All short dipole antennas will have a bandwidth narrower than a full size half wave dipole. Therefor, an antenna tuner may be helpful. The AS-20 is best installed as an inverted Vee. [. . . ] The wires must be cut approximately 2 - 3 feet longer than the dimensions shown in figure 1. This is to leave room for the hookups and tuning adjustments. Here are the lengths that you should cut (including the 2 - 3 ft extra). Cut two wires 11', two wires 4', and two wires 3'. 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. Attach the 11' segments to both sides of the center connector. Attach the 3' segments to one side of the TR10 traps. Attach the 4' segments to one side of the TR15 traps. (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. Make sure that you make temporary connections as shown in figure 3. This will leave each wire segment with one end permanently soldered, and the other end temporarily connected for adjustment.
