P3P Lost Signal in approx. 272m

[Aryo]

Hi,
Here's my flight log from yesterday. As confidence grows from practice for the last month without camera, I want to test distance and altitude. I didn't expect the signal to lose at approx. 272m. Thank god GPS are strong and RTH kicked in perfectly.
There's a cell BTS tower about 300m north of G point mark
RC Antena set as per instructed, the flatside body facing drone, tip directed inwards.
There were some people also flying fixed wing gliders in the area and seem to have no significant trouble near the BTS, that's what makes me wonder, is there anything I missed?

Any thoughts or tips?
Thanks

Try a different location to see whether you experience the same problem.

yap thanks will scout for new safe location.
what do you think caused this? while other fliers have no problems in the same location.
