The satellite dishes provided by DirecTV and Dish Network are grey, smallish, and they don't really detract too much from the appearance of older San Francisco buildings. But if you live in the UK and don't like the look of a conventional dish, then this flat rectangular box (48cm x26cm x7cm deep) from Sqish might just be the ticket. Send Sqish a photo of the wall behind the mounting location, and they will send you a Sqishoflage sticker with your order.
Starting at £150 + £25 for the vinyl sticker.
