Type ACX675-11 vertical spring hanger is used to support the
weight and accomodate the differential expansion of 6-1/8
in rigid transmission line. 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. |
