On distance more than 40 km disgustingly work the nv2
Sharply level of a signal falls and level of noise raises. Inclusion interface deenergizing helps
on the bridge rx -70 to -84 noise -115 to -97
on the station bridge All in norm

You interchange the position of base and client options
The picture changes too

I can help with testing nv2 on distances from 40 to 60 km

MT guys any chance you will be fixing the disconnects soon?
2

Also found that on my 43km link signal was very poor until upgrading to V5 do get disconnect, no beacon received now, though. However with NV2 pings higher with high spikes every so often, with 802.11 pings not higher than 3m/s.

You can show options and schedules?

On distance more than 40 km disgustingly work the nv2

What antenna’s are being used?

5

32 db grid dish.

6

32 db grid dish.

My understanding is
A grid is = http://www.interprojekt.com.pl/gold-wireless-goldsad56030-5ghz-30dbi-grid-antenna-p-363.html?currency=USD

A Dish is = http://www.interprojekt.com.pl/gold-wireless-goldsadd56034dp-5ghz-34dbi-dual-polarization-p-721.html

A mesh dish is = http://www.rfhamdesign.com/products/parabolicdishkit/1682909a390cc1b03/index.html

But not sure what a grid dish is?

OK (sorry don’t read Russian? ) but my guess from those links, you using a solid 1.2m offset dish, designed for (Диапазон частот, Ггц: 10,95-12,75 GHz) a Антенны стандарта MIMO onto this dish and using cable (8D-FB PVC - коаксиальный кабель 50 Ом,)

9

you have 3 links total and those are the data-rates on each link?
What nv2-cell-radius you tried on each of those links and what udp speed and ping times you saw?
