Line Section
A coupling kit is required for connecting the line section to the transmission line. The coupling kit will be similar to
one of the coupling kits shown below. Review the following and refer to the diagram to install the line section.
1. Locate the line section so that element sockets are oriented for easy access.
2. Be sure center conductor anchor bullets have been positioned with insulators prop-
erly seated in the counterbores.
3. For flanged connectors, tighten evenly around flange to obtain a firm uniform con-
tact.
4. For unflanged connectors, bullets should firmly seated in the center conductor. The
ends of the line section should be butted snugly against the ends of the transmission
line.
5. Position clamp bands approximately 3/4" from ends of sleeve and tighten securely.
6. The coaxial line should be continuous with no bends or offsets in its axial line.
