I am flying FPV with a 900MHz,500mW Video TV using a 8db patch antenna at receiver (links below) and inverted V antenna on my model. The navigation camera is a Sony CCD 420 lines. Range is acceptable for me, usually flying at max 500m from home, no interference.
I need to have FPV for the second model and I am thinking to try 5.8GHz.
What should I expect as range or quality from 5.8GHz comparing to 900MHz, using the same camera for navigation?
