Mate do i have just the right thing for you, but it requires some soldering. It’s also probably cheapest solution working over longer range than you need

First you need two directional antennas. Use this lea.hamradio.si/~s53mv/wumca/cup.html the 13cm design specifically. They’re using hard to get semirigid coax but you can really just use common RG178 with braid tinned to make it stiff. Good way to get this would be getting a pack of u.fl-SMA pigtails, which you can also use for connection.

You also don’t need special aluminum housing like they do, cookie tin of the right size would be sufficient, or any other container of similar nature. If you can’t weatherproof it, putting it inside on windowsill is also fine

Then, plug TL-WN722N into it, or some other single-antenna thing, and you’re set. This one connects over USB and has removable RPSMA antenna, so you can connect it easily with correct cable (SMA plug - RPSMA plug)

to your new directional antenna. This thing works well over 200m distance, provided clear line of sight, and probably more than that
