Nice link guys,

It must be quite low noise where you have those links.

Congrats guys,

what’s was the antenna gain? Was it the grid antenna in the photos.

What are your signal strengths?

One side -62, other side -70, still needs more align…but strong link.

Hi,

Free Space Loss for 74Km@5600MHz is roundabout 145dB. So (without any cable loss) if you have -62 receive gain that mean you work with 51dB TX-Power EIRP. Don’t you have any kind of regulations in your country???

19dB TX-Power from card + 32dB antenna gain ./. 145 db FSL + 32dB antenna gain = -62 at receiver
