The conduit on the far left side is for coax for a sat dish that no longer exists. The conduit really was just for down the post to protect the wire. It doesn't run underground. The wire was, assumably, direct burial. Either way, it's not used any more. The conduit on the right side, with the yellow cat 6 running into it only goes about 6" into the ground. Today I ran a temp run for a phone hook up, and the conduit is just to keep the guys that mow the property from cutting the wire. I barely got the wire below the sod. But before I did this, the phone line ran from the D-Marc to the #2 RV just on the ground, when someone was there. I've got a roll of direct burial cat in the shop and will rerun the wire in a couple weeks when I get back on site.
