I was exploring the swamp - made a wrong step and got stuck.
I revived into Saransk West outpost (as expected).
However, the antenna connection was lost ... even though it was only a few minutes running distance away.
To regain the signal - I had to stand under the antenna (again!), the Signal Strength remained at 3% until I was a few meters from the antenna.
No re-connection message was chatted back to me as a system message.
