I want to send satellite tv from one room to another. this would be done using 2.4ghz tv senders. but due to the numerous thick concrete walls inbetween the two positions i would probably need to do this outdoors as both have windows on the same side. anyone done anything like this? i would imagine that the antennas would need to be extended or new antennas fabricated and so they were fixed on the side of the building at both positions.
