the clint is 2.4 km from high site signal at hige site -80 and client -82 what i want to know is this a good signal or not for there will be clients 8km from sector as well
Increase the height of the client would be my guess.
I would have to make an assumtion, based upon the lack of information, that something is infringing upon your freznel.
Based upon the levels and distance I would have to say that just by raising it by 3 - 5 feet should net a big improvement.
What heights are you antennas at?
What is the terrain (trees, buildings, etc.)?
