I have a signal problem PTP link C5x, 3km distance

Migrating from Nanobeam5AC 19 to C5x with N5-20. The signal level with Nanobeam is -61dBm. With the new C5x equipment I have a level of -80dBm. Any idea how to get a better signal?

Set your power manually. We have a 4.2km link and set our power Tx EIRP/ Tx conducted to 41/21 dBm, working great. Check your alignment also.
