My question involves landlord-tenant law in the State of: California

I would like to know if it is legal for a landlord to force tenants to use only one cable provider. I moved into a one bedroom and didn't find out until after that the landlord does not allow the use of dish providers. Due to my location there is only one cable provider for my area. I previously had this carrier and would not choose to have them again. Can the landlord actually force me to have services with this provider even if there is no mention of this in my lease?
