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
