The tests were performed on a link in operation, to see the real immediate benefit, and to define a useful data to take it as a reference for future links, because the antennas were replaced, it was not possible to make simultaneous tests, for that reason, it is considered a preliminary test, the tests were done with the feeder at 90 degrees, we need to test at 45 degrees, we tested 1 month with the feeder at 90 degrees, we will change it to 45 degrees and in a month we will have the average of the tests.
