Need 8km p2p connection using 2 NS5M

[bouncer]

Hi,

I need to connect 2 location 8km far from each other. I have clear line of sight. One location is top of mountain and other is sea level. I like to use 2 NS5M to create the link. 10Mbps connection speed will be fine for me. Please suggest me if there is any problem or I need higher db panel?

Quick math shows signal strength as low as -65. With the antenna beamwidth what it is you might pick up a lot of noise over that distance, but if that isn't an issue, you could see speeds a lot higher than 10 mbps. I would say 40 mbps should be relatively easy to acheive on 20 mhz channels.
