This is a mom and pop cable co. in a very small town. According to the owners of the apt. building there is no contract giving him exclusive rights to supply the cable. Want I want is to be able to access the the home run wires to install satellite in the building to residents that wish to have it instead of having wires running through windows etc. He claims the box is his because he installed it, and is denying access for this purpose.
Well, unless he has an agreement with the owner of the building that the box became the property of the building owner, it is still the cable guys box. Although the cable guy may not have exclusive distribution rights within the building, what is there is still his property unless there is an agreement to the contrary. He obviously has permission to install and run whatever he has installed.
This would be similar to a phone company setting up distribution within a building. Another company cannot simply come in an utilize that equipment without permission of the owner of the equipment.
You do not intermingle different companies systems on a common system.
Who would you expect to maintain the wiring in place now? If you did use it, who would maintain the infrastructure?
If you want to run satellite, you willl have to run your own set of wires
