I am getting ready to dig my pedestal for my steel pier. I am planning on running conduit for ethernet and direct burial 12/2 electric wire in pvc conduit in a 18" deep trench and into the concrete pedestal and into the bottom of the steel pier. The observatory is 72 feet away from my house and electrical panel. I have thought about using fiber but do not want too many additional adapters and fiber to ethernet converters so I have decided to use cat 6. Does anyone have any advice for conduit? I already have 3/4" conduit for electrical but still confused on cat 6. I originally thought 3/4" but am now thinking about using 1 1/4" for a couple of lines or maybe even change to fiber something in the future. People seem to advise to use fiber for protection from lightening strikes. I have seen several people discuss installing inline ethernet ground blocks for surge protection but gives no advise on how to ground them. Seems like there needs to be a grounding rod. Other people say they have installed cat 5 or 6 without any grounding and never had a problem for years. Maybe I should install 3/4" conduit for one cat 6 cable as originally proposed and take a chance by unplugging the cable from my router when not in use. I get sufficient wifi for my security camera so I do not really need two cables. I assume I can pull new cable with the original if needed. I just want to have my mini pc hardwired when imaging. In the past I used an extension cord for electrical and wifi. I was a pain when mowing. Thanks for any advice.
