In major metros it is really hard to get roof rights. In larger buildings HOAs even have exclusive agreements with cable and satellite resellers that install a single set of equipment for the entire building.
You are trading one set of ridiculous laws for another.
Supposedly those exclusive deals are no longer allowed:

The solution above would suit my needs and work for where I live.
It most likely wouldn't be able to scale to cable company levels, but it would be a great small to mid-size local business. One that could be replicated in cities across the nation.
NetBlazr sets up WiFi antenna's on rooftops now. While you set up my Internet antenna, please set up a TV antenna for me - one I can access streaming via the web. I only pay for Internet service and a one time TV antenna set up fee.
Now if this company, whether it be NetBlazr or Aereo wants to offer more channels via their web site where I watch my local channels then great! I just might buy more channels.
