What is the Diameter of the Pole in the Weather Meter Kit?

Hello SparkFun Team,

I recently inquired about the Arduino IoT Weather Station and was directed here by Joelle for technical support.

I have one question:
What is the diameter of the pole included in the Weather Meter Kit that comes with the station?

This will help me determine mounting options and whether I need any additional hardware for proper installation.

Thank you for your help!
