Wireless bridge between two buildings: Hardware suggestions needed

[Rock]

I want to put up a wireless bridge between two steel buildings.
Line of sight is clear.
Distance is 270 feet.
There are no viable options for running cable.
Wireless devices can be high enough on the exterior walls to avoid vehicle interference.
The switch feeding this network segment is Gigabit Ethernet, without POE.

I spent some time on the Ubiquity website, and have used their products before, but I did not find a guide to show which device is ideal for which distance. (and many products are out of stock)

My question: What wireless hardware would you select for this wireless bridge?

Edit: Distance is 270 feet.

If regulations in your area allow it, look at 60GHz hardware i.e. from Mikrotik MikroTik
Latency and reliability is superb compared to WiFi.

200 feet with clear line of sight, if you could mount the receiver and transmitter pair external to the building.

It is piece of cake, you could just pick any airmax , even cheap airMAX NanoStation 5AC Loco

Should be super easy even with consumer grade hardware

These are supposed to be pretty decent - TP-Link's 2.4GHz CPE210 and 5GHz CPE510 outdoor bridges.
