94.11   Pole Top Extensions

 

If a pole top extension is installed, the length of the extension shall be added to the length of the pole to determine the required depth in accordance with Rule 49.1-C. For existing poles, if the depth of the pole is not adequate to support a pole top extension, the extension shall not be installed.

 

Final Version

Rule 94.11

 

94.11   Pole Overturning Calculation

 

A pole overturning calculation shall be performed before a pole-top antenna installation is added to a pole. The calculation shall use a safety factor of 3.0 for Grade A construction, and 2.0 for Grades B and C construction, and incorporate loads for the entire pole structure, including all existing attachments and guys (if any), and all elements of the planned pole-top antenna installation. After the installation, the safety factor shall comply with Rule 44.3.

 

Note: The purpose of this calculation is to ensure that the pole overturning moment does not exceed the capacity of the soil, rock, or other material in which the pole is embedded to resist the pole overturning moment.
