I was saying 1 to 1 1/2, but did read it after posting. As long as in a location that is deemed an exclusive area to the consumer, and is placed without any damage to the building, the landlord can not say no. This would be something like a balcony, or terrace on a tripod, or I saw my buddy do a clamp mount once, but that was the only one of those I had ever seen and required a lot of zip ties. In that case, if no holes are being drilled, the landlord has zero say to a consumer getting a dish installed.
Now if it needed placed on a room, or cables drilled through or even just cable clamps on the building then the landlord has a say, and can ultimately deny. But he can only deny the structure damaging portion of the install, not the install itself.
