I am putting up a p2p with near to perfect line of site. Distance between points is 9km. I need at the least 150Mbps. I am considering QRT 5 for this link. I need professional advise from those that that have deployed this unit.

I am particularly worried about the distance and would like comments on this. Also would appreciate any suggestions for alternatives. Would Netmetal5 combined with mANT30 be a better alternative for this?

Hope already solved the prob, if still not can advice.

if the LOS and Height of Tower are at same level almost QRT-5 will work, if not then off course Jumbo Mikrotik will work 100%.

QRT should give you that performance depending on RF conditions.

If spectrum at the location is crowded, your best bet would be a RB911 or 912 in a very good antenna RF-Wise, like jirous JRC24 Duplex or JRC29 Duplex, with RB in an aluminum enclosure like JR-250 Alu to further protect from RF.
