Hi there, I am trying to create a wireless trunk between several buildings on my site. They have line of sight and the following chart summarises their relative location.

Are the equipment I am planning for correct? Is the 15s adequate or do I need the 19s. Thank you

You have a good point. SXT SA5 ac or mANTBox 15s will be enough for you. You can get approximately 250-300 mbps on the 40 MHz band or 450-550 mbps on the 80 MHz band

Ignore all and use 60Ghz....

Thank you both. I am not familiar with the 60ghz. I will research it.

If price is not of any importance, indeed 60GHz gives better performance.

I split 2x 60GHz links (Cube60) , connecting 3 hubs, with 6x SXT SA5ac to 18 SXTsq5ac. Excellent performance (260 Mbps on 40 MHz band; NV2; +-150m distance) (1Gbps on Cubes)
Price is/was a major factor.

Antenna Gain SXTsq5ac and Mantisbox15s are well balanced.
3 Hubs because of houses in the path. Avoid trees .

yes, for short distances 60ghz is the way

60ghz is indeed interesting.

For around 180mtr distances is the wAP-60G-AP / wAP-60G combination sufficient? It seems that this is on the maximum end of the stated distance.
