Hello. I need create difficult wireless link. Between two points there is a big hill. I want use two mANT30 as passive repeater on the hill.
A to B = 14 km, B to C = 8 km. Passive repeater in B point.
In A and C points: mANT30 PA + NetMetal5.
Need stable 20 Mbit/s.
Do you think this is possible?

Do you think this is possible?

Hardly.

Passive repeater ideally transmits all energy received by one antenna over the other antenna. If AP at point A transmits signal at +30 dBm (includes antenna gain) and potential station at point B would receive that signal at say -40dBm (which includes antenna gain), that's exactly the signal power available at antenna port of the other direction of passive repeater. Including antenna gain that would mean TX power of -10dBm (which is 40dB less than Tx power of an active repeater). This loss of power translates to low received power at point C - RX level at some -80dBm, which IMHO doesn't guarantee 20 Mbps transfer rate.

My calculation might be off by some 15 dB in each direction ... so things just might work, but it really depends on details of particular setup.

Thank you very much. We will try to create this link. I'll tell you the results later.

If you have the Space go with the biggest Antenna you Are able to buy
