Antenna Mast Roof Mounts
There is no substitute of height, clear line-of-site and size does matter... The higher the frequency, the higher the loss... Amplifiers do not give you something that you didn't have already...
The first key to any reception is to get above obstructions that exist between you and your target, as radio frequency reception of any kind (satellite, microwave, Radio and TV) are for the most part "Line-of-Sight" dependant. The fact that some receptions occur without line of sight is due to phenomenon not applicable in this discussion. As you increase your target distance, you increase the territory you must account for in maintaining line-of-sight.
What tall building and air traffic exist in this corridor, no one can account for. Aircraft are very good at messing up reception for a number of reasons, even when flying way above the path, again removed for clarity in this discussion. Height, is therefore key in optimizing your ability to capture the best line-of-sight possible to your target.The Roof of any Building of Home provides a Logical Platform of Height in which Line-of-Sight is more likely to occur, or from which, more height can easily be obtained.
