What is appropriate value for 3DR Telemetry module radio RSSI?

I searched my house and found some old telemetry equipment.

This works, and I am sharing the ordinary good values for the AliExpress V5 module.

The antennas I have all seem to be 433 MHz, while the tested module is 915 MHz. I think that’s why I struggled so much. All the antennas I have look identical.
