My LR Mode Range is only 60m

Hello,

My LR Mode Range is 60meters only. Any suggestion? I use WROM 32 as receiver and ESP32 Cam as sender. Testing environment is open space and clear line of sight in the city.

I use code from here: https://github.com/jnogues/ESP32-Long-Range-WiFi

Any suggestion?

Thanks
