Invisible Satellite dishes

Actually they are not hard to see, but their shape is unconventional (like a square or rectangular flat box), which translates into seeing something that does not look like a dish, which could be less intrusive. Supposedly by painint them the color of the waall behind them they become less intrusive. I don't know about how effective they are but I imaagine less so than conventional dishes. In the end it depends on how big the 'dish' and which satellites you want. Sorry, I can't help there.
