Would anyone have advice (layman's language) for getting the wifi signal from my house into a metal building (my radio shack/metal shop/cigar lounge)? I'm only a SDR listener but wifi is necessary (duh) to use it.
I'm struggling to find info on the interwebs that explains if things like a yagi or other external wifi-specific antenna will receive as well as send.
My situation is:
5G wifi router in the house that broadcasts very well. I can get 3 out of 5 bars outside the building 75ft away.

The house is stick built, and router is inside but towards the end of the house facing the building. I can't do a trench with cable - too many obstacles. Ideally I'd like to put a decent quality exterior antenna outside the building to better pick up the signal. Putting at exterior antenna on the router is an absolute last resort - pushback from the missus.
What I'm not finding is information detailing if signal can be sent back to the house router. Do some models of exterior wifi antennas boost the signal going back towards the router?
Thanks.
