i have 2pcs XST hgnr2 connected successfully at home but the signal is poor when mounted 3 km apart .
the question is : will they transmet internet that far ? and how much i would get max ?

other qustion is what mode to choose , station , station bridge , cpe station wds .. and so on .

i did googled alot and found lots of information with different configurations that made me confused .

Sxt5hndr2?

I think he meant RBSXT-5nDr2, that thing should be good for 10km, I personally never gave it a try, but by the specifications and by some posts here it seems possible. I would use CPE for this.
