I use a "cubsat" to get SkyDigital. I'm not allowed a satellite dish either due to planning laws, so I ordered a Cubsat 70 from

It's basically a dish hidden in a box that sits in your garden - nobody has a clue what it is, and it's not fixed to anything. It works a treat (I'm in Bristol UK). You need a line of sight to the Satellite - I think it's 28.2 degrees East, or thereabouts.
Doesn't answer your question, but just an option you may not have considered.
