Thanks, folks. Yes, I'm in East Texas. The pole seems steady, and is in the ground with a bit of concrete, a bit over 2 feet deep.
Here's a grounding question. There are four cables coming from my dish. A twin cable goes to a HD/DVR unit, and one cable goes to a bedroom HD unit. The fourth cable is for possible future use, and terminates at the ground block. The twin lead has a solid copper conductor along its length. That single copper conductor is grounded at the grounding block. At the dish, however, it is just blowing in the breeze - it is not attached to anything. Should it be attached to the dish mount somewhere for grounding? If so, would attaching it to one of the three bolts that fastens the the dish mount to the pole be a good attachment point?
