I have been working on the plans for a 1.2 ghz fpv antenna tracker for long range missions. It will have a 10 element yagi antenna and a range of about 15 miles. I plan on measuring the rssi values from the receivers with an arduino board and programming it to run a servo aiming the antenna horizontally. Is it possible to use only 1 receiver as opposed to using two or three different receivers? This is to try to cut down costs for the whole project.
