By: Jay Nugent - WB8TKL	- Trenching Cables to the Weather Mast -	Latest Update: Aug 30th, 2012

Back to the Home of my Weather Pages NWS Standards references and white papers Weather Mast design and construction details Gill Box design and construction details Trench to the weather mast Junction Box to terminate all data/power cables Instruments inside the Gill box Tempurature/Humidity Aspirator Sferic details...

Since trenching cables underground is rather labor intensive, bury as many cables as you would ever expect to use! Bury spares in case some varmit nibbles on a wire. It is FAR easier to do it now, than it will be to RE-trench new or additional cables.

I opted to bury the following cables:

• 120 vac - for power supplies, de-icers, future unknown devices that may require it.
  I also added a waterproof "Bell" box with a duplex outlet. Ya never know when you might need to run a drill or a weed wacker!
• 12 vdc - 12 volts DC for running the ADS-WS1 controller, LED lighting, low-power single-board computer (Linux).
• 22 gauge, 2-conductor - This is for an Ademco type #39 magnetic switch. There may be valuable equipment inside the Gill box and knowing if/when the Gill door is opened would be nice to know. So this will tie into my home alarm system.
• Cat5 - This cable will be used to pass the RS-232 data from the ADS-WS1 controller back to my Linux PC in the house.
• Cat5 - This cable may be used for a future Ethernet, or may just be used as a spare cable if needed.
