Skydemon drops connection via GDL 90

Sorry for the delay in posting this, but I finally completed the install of the router and gave it a good functional test, although I plan to also do a more scientific test in the future. I installed the MIMO antenna on the underside of the aluminium fuselage of my Savannah and the router inside the cabin (see photos).
What I can say for now is that I have done two flights at over 3000ft, including over a sparesly populated area which probably only has average mobile coverage, and appeared to have a good connection for the whole flight, based on being able to see traffic every time that I looked at my Skydemon map.
I will figure out a way to check the connection and log it to a file so that I can get some good data. If anyone knows a free app for Android that would allow me to check my connection and log the results, please speak up.
