I have just had two PTP820S 1+1 links installed, and during the alignment process, it was noted that the primary and secondary have an approximate dBm differnece of 3-6dBm.
So for example sake, I have the Primary talking to the other Primary, RSSI at each end will br approx -45dBm
When a Primary on either end is talking to a Secondary, the RSSI at each end will increase to approx -48dBm
When both Seondary units of the link communicate, the RSSI at each end increase again, up to around -51dBm
Is this normal play for the PTP820s, as they both are directly connected to the antenna via a coupler, operating the 11 GHz range.
Does the coupler deliberatly have a 3dBm loss for the Secondary?
Thanks for the help.
