Description
Type ACX675-13 rigid hanger is designed for mounting 6-1/8 in rigid transmission line. Type ACX675-13 hanger is used to anchor up to 1000 ft (300 m) of transmission line. An additional hanger should be used on the top section of the vertical run for every additional 1000 ft (300 m) of line or portion thereof.

Rigid Hanger Installation
Note: If no holes are available, contact the tower manufacturer for applicable safety regulations regarding the drilling of any holes in tower sections.

Transmission line installation may begin at either end of the proposed vertical run. Installations originating at the top (antenna end) of the vertical run will require at least one rigid hanger at the top (depending on the length) and will require proper positioning of the bottom miter elbow to allow for both expansion and contraction of the rigid line over the anticipated operational temperature range.

Installations originating at the bottom (transmitter end) of the vertical run must utilize one or more rigid hangers for support. Additional miter elbows and field flanged sections will probably be required to ensure alignment with the antenna input flange.

Note: Rigid hangers used at the bottom portion of the vertical run for increased support during installation must be removed after installation of top rigid hanger(s) to prevent serious damage to antenna and/or transmission line.
