I would not use that, wifi bridges have came a long way since that was introduced. I would use a pair of directional POE wifi bridges, then add a basic wifi router running in accesspoint mode inside the second building. I am doing something like this with our shop building on the family ranch, which is about 1,000 feet from the main house, and am getting effective speeds up to about 60-80 mbps there when Starlink is getting around 130 mbps at the main house.
I was initially using these https://smile.amazon.com/gp/product/B072Y5S8YX/ with one of these little access points inside the metal shop building https://smile.amazon.com/gp/product/B0167N0B70 until the shop building took a direct lightning strike frying the equipment on that end, I replaced the stuff at that end with an omni directional extender https://smile.amazon.com/gp/product/B08C4QCWC5 and then upgraded the unit at the house end with a Micro-Tik POE directional unit when the unit on that end became unstable.
