If you are using the mushroom antenna on the ST16, it must be pointed straight up. I prefer the square flat panel antenna for a better signal. The flat surface must be pointed directly at the drone.

Thanks, yes I have the mushroom antenna and probably that was the reason. I will check antenna alternatives. Of course this may be a non-problem with my normal flying and what I saw only an unfortunate glitch.
This is the radiation pattern of the mushroom antenna. The orientation is important for good reception.
At the end of the first video it appeared that the mushroom antenna was in an acceptable position. If you continue to have issues with WiFi reception at short range you can check the matching antenna in the CGO3+ behind the front lens cowling. There have been instances where the shield separated at the base of the cloverleaf.
This can be repaired by stripping about 4mm of the outer plastic insulation then using a fine copper wire to wrap it from the insulation up to the base of the cloverleaf. Next use a small amount of flux and solder the wrapped area to restore continuity to the shielding.

While not strictly legal in European countries you can also try using the US CGO3+ firmware to have increased WiFi power for the 5GHz camera communication.

Thanks for the info. I think I will simply start doing a few more flights using the orientation information above. It is perfectly possible that I found the "hole" in the radiation pattern due to unsuitable orientation. Again ... first try to replicate the error ... if it works don't fix it

They were just suggestions of things to try if the short range dropout continues. As @Steve Carr suggested the flat patch antenna (on the ST16) gives better range with a narrower beam than the cloverleaf does.
@larsesilen, to give you an idea of the normal range for the CGO3+ (using US firmware) over open ground at an altitude of 30m I would get to 500m distance before I would get lag or pixelation in the video feed to the ST16 using the cloverleaf antenna. When using the patch antenna under the same conditions the distance was 1km.
I did a new test flight actually two flights. In the first a Typhoon H480 with a CGO3+ camera was used. Originally there were 5-motor faults on the H480 but changing the main ESC board solved the problem probably caused by a damaged MOSFET power transistor on motor #1. The video problem with viedeo drop out I saw in the previous flight was clearly solved by pointing the mushroom antenna straight up as instructed above. I guess that by pointing the mushroom antenna directly towards the H480 I happened to find the sensitivity hole causing the signal to fade out. Thanks for the instructions!
The second flight was done using a Q500 4k with a CGO3 camera. The weather was cloudy but no rain. The wind speed was roughly 8 m/s which is OK for these fairly big drones.
On the second flight I connected an Android Pad (Lenovo P11 second gen) as a parallel display to the controller's display. The CGO app (V0.1.0.0057) seemed to work flawlessly. The app showed video from the Q500 4k at the end of the flight which indicates that the WiFi connection was unbroken during the whole flight, it seems the app isn't able to re-connect if the WiFi is broken even for a short moment. The re-connection problem may be dependent on how the WiFi is configured on the Android Pad.
The flying area is Glasdalen in the town of Espoo some 20 km to the west of the capital Helsinki. The latitude is 60 deg N. I stayed within a fairly small flying area to ensure that I would be able to pick up the drones in the case of some technical problems. Especially this was the case regarding the newly repaired H480 that worked flawlessly. I was able to test automatic panning using the H480. I think the slow panning wasn't completely clean possible as a result of not being used for a number of years ... time will show if cleaning will be needed.
The flying area is used by gracing cows in the summer. This means that if what you look at looks like BS then it is BS ... Moving around on the ground requires a visual check before putting the foot down .
My personal feeling regarding the H480 and Q500 4k is that the H480 is technically more advanced and more responsive. The weather was OK for both drones and the video quality of both drones is very good and very similar for obvious reasons. My feeling is that there is a small difference in the White Balance settings with the Q500 4k producing a slightly warmer image. The CGO3 and CGO3+ cameras are very similar. I plan to do a third flight using a Q500 with a CGO2+ camera when there is a suitable similar weather. It may be interesting to compare the CGO2+, CGO3 and CGO3+ cameras. The video mode was 1080p that is not full 4k even if it is available. The reason for not using 4k is simply that I don't have any display that could show 4k video at the stated full resolution. Of course the file size produced at full 4k is extremely large.
For people interested a link to the uncut videos is given below. Warning the video is fairly long and there isn't anything really exiting only two very similar flights comparing the drones.
