The signal strength is from the client. Tx signal is of course your signal strenght – this is reported back to AP by the client. If your client is not RouterOS, you won’t be able to see your tx signal strength.
Different signal strengths sometimes indicate misalignment.
If you have a north-south link and the south end points (example) 15 degrees east, it (south) will hear the north side almost as good as it would have pointed exactly at each other. However north wont hear south as easily as much of the energy is going in the wrong direction.
but doesnt that make the south antenna have less gain in the way of the north antenna, making the south antenna hear equally less power as it is putting out?
because the gain pattern of the antenna affects how well it hears, and how well it talks.I thought…
