DirecTV's standard installation is a roof mount for the antenna. If you want it on a pole set into concrete in the ground, then you get to haggle/negotiate with the independent installer (not a DirecTV employee) on the cost that will be charged...........when he shows up to do it. I tried to get a quote up-front ("Have the installer call me in advance....") - didn't happen. I've run into this with two antenna installations with DirecTV (one in OH, the other there in TV). Some folks manage to get the installer to do it for free. Others (like me).....no such luck.
The guy up here in OH did an excellent job with the antenna install: He dug a fairly deep hole, flared it out a bit at the bottom (to help keep the concrete from lifting with the seasonal freeze/thaw cycles), filled it with quick-set concrete, screwed some long bolts into the pole that would be within the concrete to give the concrete something to grab onto - couldn't have asked for anything better. My cost: $75, paid directly to him. I was fine with it. Different story in FL: Pole just pounded into the ground - thank you very much. Not happy with the job of running coax to entry point on the house (I wanted it tucked up under the siding which he agreed to, came back to see how things were going after a bit and he was just screwing cable clamps into the foundation blocks - the lawn guys have to be really careful now), plus other issues as well. I wasn't really happy about it overall, mostly concerned about the wind potentially shifting the antenna and the coax exposure - so far, so good. My cost: $25, again paid directly to him.
You're pretty much on your own with whoever the installer is when they show up. Hopefully, you'll get a good one!
