Television is simple enough. They are also unsightly in many older homes with the coaxial line running from a box outside the building, and a hole drilled to snake the cable through the wall. This is not how it should be done. Coaxial lines will run from the communications closet to the appropriate rooms. This will all be behind the walls, and out of sight. The would connect to a wall jack in the wall, and be as clean and efficient as possible. All coaxial lines will be RG6.
In the communications closet, the television network will be decided whether it is Comcast, Verizon, or OTA. This selection will apply to all TVs in either the business, or residence. Each entity will have their own choice. This means cable TV could be installed for the business, and therefore deducted as a business expense while the residence will rely on the OTA antenna which will be on the roof of the elevator room.
