I recently fitted a reversing camera and screen to the people carrier. The idea was to use wireless coupling between camera and screen. It failed, as the wireless range was in the region of 10 ft in free air. Anyway with much cursing I hard wired the video in the car and put the wireless bits on one side for further investigation. I found this week, when I checked the transmission frequency of the transmitter that it was putting out 3.69GHz, which I believe is outside the 2,4GHz band. I checked the frequency counter with another sender operating on channel 1 and came up with 4.1GHz, which is in the right ball park. Does anyone have any experience of this type of off frequency problem? The antenna length is 38mm, which seems a bit long but may be based on experience. I can't find any references to people using 2.37GHz for video sending, anyone know otherwise? The unit is Xtal controlled.
