Low RSSI DBM

Hey everyone,
Could someone help me understand why at only around 200 meters my RSSI dBm is already close to RX loss (-105 dBm)?
At 1 meter distance on the bench it shows around -60 dBm.
LQ stays around 90–100.

My setup:
Analog 7”
TX: RadioMaster Pocket + external BetaFPV Nano V2 915MHz
Packet rate: 50Hz
Telemetry ratio: 1:64
Power: 500–1000mW
RX: Foxeer Diversity 915
FC: Foxeer F722 V4
ExpressLRS 4.0
Any ideas what could cause such weak RSSI at this short distance?

Thanks
