Loading coils are wound on top of weatherproof plastic, and covered with a heat shrink sleeve. [. . . ] Assemble the sections of the antenna together paying attention to the figures. The wire segment lengths shown in the table are your starting point for tuning the antenna. When you cut the wire, leave plenty of excess for making connection and lengthening if necessary. Make sure that you make temporary connections as shown in figure 3. Raise your antenna, and check the VSWR on the highest frequency band first. If the resonant frequency is low, shorten the wire segments. After the desired frequency is achieved, make permanent attachment for these segments as shown in figure 2, trimming off excess wire. Repeat this procedure for each band, going from highest to lowest frequency. WARNING Outdoor antennas and lead-in conductors from antenna to building shall not cross over electric light or power circuits and shall be kept well away from all such circuits so as to avoid the possibility of accidental contact. Where proximity to electric light or power service conductors of less than 250 volts cannot be avoided, the installation shall be such so as to provide a clearance of at least 2 feet. Where practical, antenna conductors shall be installed so as to not cross under electric light or power conductors. Figure 1: Wire and trap arrangement (one side only). Refer to table.
