I bought a netmetal ax to replace the various ptp of my network.
On a 7km radio bridge, I currently have with my old netmetal ac, I have a signal of 44 dbi.
replacing the netmetal ax the signal reaches 74 and obviously the link is ko.
The bad thing is that on the state of the radio it transmits between 20 dbi or 28 dbi, it depends on the frequency set.
How is this difference in signal possible?
