if towers are 15-18 meters, if you use a 29dbi antennas (like jirous 29D) and you use two routerboard 411AH with radio N 20dbm, if youmount very well all, you could expect 40Mbit inone direction

For 18mbps you can use RD30 and RB711 dual chain. Is cheaper and speed will be over 18mbps. No need for RB411AH because at that distance a faster cpu or ap licence will not help you.
