Question WiFi Network coverage hardware advise

[Redicliff]

We are currently running an old Belkin router as a hub to an elderly Apple Extreme (A) to reach an outbuilding (B) 100 ft away with an elevation drop of 15 ft and minor line of site obstruction.
At B we have a Tp-link RE306 extender which helps on occasion but the signal is too week for reliable connection.

We have another Tp-ling RE306 installed in another building (C) 200 ft in the opposite direction with a 50 ft elevation rise and significant line of sight obstruction.
Believe it or not we can get a signal there as well.

We'd like to generate stable signals at both sights B and C both for internet "browsing" and security camera network.

We're looking at mesh and extenders and presumably maybe a newer more powerful router. Of course, it's all very confusing so we're hoping for experienced advise and perhaps even specific hardware recommendations.

Advise and shared experience is appreciated

Two wired outdoor directional access points. One pointed in each direction would be my recommendation. Something like Ubiquiti nano 2.4Ghz

Thank you. I see these can come in pairs. Does one install a unit at both ends. or will a mobile devise pick up the directional signal?

You can use them in pairs as a point-to-point bridge. But you can start by using them as directed broadcast to the area you want to cover. If individual units, pointed in the directions you want enhanced coverage doesn't provide sufficient signal, then you could put a paired unit at buildings "A" and "B" to link directly. You would then have wired and wireless options at A & B.
