It is only legal for your building to ban satellite dishes or standard OTA antennas if any of these conditions are met:
1) The dish is over a meter in size (DirecTV and Dish offer dishes under this size for their modern satellite systems)
2) The building is covered by being a registered historic place and the placement of satellite or normal antennas would detract from that historic character
3) The antenna would reach higher than 12 feet off the roof
4) The building has a full TV antenna on the roof and wiring into each unit that would allow you to receive all or most local over the air channels.

Anything else, rules deriving from the Telecommunications Act of 1996 mean they can't disallow you from mounting satellite dishes or standard TV antennas, and this includes allowing them to be placed on the roof if placing them out a window or on a balcony would not allow the proper line of sight to orbiting satellites or proper reception of local market TV stations. Call 888-225-5322 and the FCC can help you force the owners to allow you to get a dish or antenna up.

(Of course satellite internet is in no way competition for broadband, just saying your building's owners are lying when they say you can't have satellite and if they ever prevented you from doing it they broke the law! Even if the cable tv/internet was included in your rent, they're still obligated to allow you to have satellite or regular antennas)
