Can a radio bridge work through a point?

Question

WiFi

There are three Ubiqutiti AirGrid 23 dishes at 5Ghz. If you plug in one that will transmit communication, direct it to the second after 200 meters, and behind this second there is a third after 500 meters, will this third dish receive a signal?

Answer 1

NO
AirGrid These are highly directional antennas.
If points 2 and 3 are in the beam opening field of point 1 and are directed to point 1, then both will receive communication from point 1.
If point 2 is a bridge, then one more AirGrid is needed in position 2 and scheme 1>>2-3> >4 where points 1-2 and 3-4 are directed at each other, points 2-3 are connected by a cable.

Answer 2

From the wording of your question, it seemed to me that you think that the device at point 2 will itself work as a repeater or repeater (repeater). No, it won’t happen by itself, it will have to be configured for this. Moreover, it is not a fact that such an option is provided for in it. But in the device you named, it definitely won’t work, because usually repeaters have antennas with a circular pattern, and therefore, they are short-range, and repeaters must have a pair of highly directional antennas (and here is one).
But you don’t need this - point 2 in your circuit looks superfluous in general, you can immediately work from 1 to 3, at a distance of 700 m, if the energy of the communication channel allows (that is, the power of the transmitters and the sensitivity of the receivers will be enough for stable operation, this can be checked empirically - after all, you already have the devices). In addition, you will have to comply with some additional conditions - the absence of local objects shading the beam, a very precise adjustment of the beam position (mutual aiming), a very rigid mounting bracket for the device (so that the beam does not change position due to wind load). But this is surmountable - there is a topic on the "trunk" (already 50 pages), where everything is described in detail.
