Aloha Ligur,
This screen capture is of your Ultra running DJI GO 4 HD in Auto Mode. You have to touch "Custom" to get to the good stuff. There you can pick a lower "Image Transmission Code Rate" and even a different Work Frequency of 2.4 or 5.8 GHz. These are settings besides the transmission frequency option.
In EU custom selection is not an option by default, I think it ties in with the radio regulations and not transmitting on a fixed channel to avoid generating interference.
A quote from a Wiki article on 2.4GHz:-
Many video senders on the market in the UK advertise a 100 mW equivalent isotropically radiated power (EIRP). However, the UK market only permits a 10 mW EIRP limit. These devices cause far more interference across a far wider area, due to their excessive power. Furthermore, UK video senders are required to operate across a 20 MHz bandwidth (not to be confused with 20 MHz deviation). This means that some foreign imported video senders are not legal since they operate on a 15 MHz bandwidth or lower, which causes a higher spectral power density, increasing the interference. Furthermore, most other countries permit 100 mW EIRP for video senders, meaning a lot of video senders in the UK have excessive power outputs.[ |
