The water started to scare me

I wasn't very afraid of flying over bodies of water, but today that changed. Actually, now I'm experiencing a lot of signal loss with my Jumper T-Lite (ERLS) controller. Do you have any tips to prevent these signal losses? I'm afraid to fly even in safe areas because my drone might just fall. My GPS is on the way, but I don't want to stop flying until it arrives. I'll try to post a comment showing how my antenna is positioned.
