No park owner, after the effective date of this amendatory Act of 1987, may require a tenant to remove an outside conventional television antenna, or require that a tenant subscribe to and pay for master antenna television services rather than use an outside conventional television antenna. This Section shall not prohibit an owner from supplying free master antenna television services provided that the price of such services, is not made a part of the rent of the tenant. This Section also shall not prohibit a park owner from requiring a tenant to remove an outside conventional television antenna if such owner makes available master antenna television services at no charge above the rental stated in such tenant’s lease.
