Last year our cable was giving us a lot of trouble, besides nickle and dimeing us to death.
After replacing our cable tv box, two modems the techs were finally sent out to do some real work and replaced all the lines coming into the house.
The meter base and cable are next to each other at least 3 feet apart at the far corner of my house. The two meters (one is the neighbors one is mine) for electricity are supported by thick conduit while the cable and phone come out of the ground about 3 or 4 feet on aluminum conduit, it almost looks like a fence post for chain link fencing. The cable is grounded to that conduit while the cable runs into the house via a plug in the wall and another from under the house. That extra cable outlet is not being used but would make a great ground or at the very least a decent ground.
I would never place a transmitter outside on that pipe coming out of the ground because there are no windows on that end of the house and I am worried about theft. Some 20 feet from my house there is a ground mounted transformer. Most all of the houses in this park get their utilities from underground.
