I have a 50 mile B11 link with 4’ dishes running 400Mbps. When the alignment is done, it should hit 480Mbps.

All the other links on same roof and other water as well used vertical polarity and had ducting issues. With MIMO and all kinds of polarity options I am sure you can find a solution. Antenna diversity must be engineered for path and conditions. Where are you trying to shoot from? On Oct 31, 2016 6:39 PM, "Cassidy B.

Seems a 2+0 at 6 would probably work at that distance.. although seawater is a factor I dunno about On Oct 31, 2016, at 18:32, Charles Regan <[email protected]<mailto:[email protected]>> wrote: Well here's SAF response: My link planning team confirmed SAF does not have a viable 5GHz radio that can achieve your objective for this path. Trango: rough calculation suggests that even using space diversity will yield a 3 - 4 'nines' link (predicted reliability) at around 200Mbps FDX. The use of space diversity will also add considerably to the cost (a complete link might be upwards of $50K). I'll ask SIAE...

Or two pairs of alfoplus1 1024qam (single polarity) radios running in parallel, opposite polarities, equal OSPF cost between routers. Or Trango's 1024QAM 6GHz radios. Why not SAF? I thought there was a 6 GHz version of the Integra now.

Oh and it's over seawater... 20k$ budget. SAF, Trango both said sorry, can't do. Mimosa B5C with space diversity and 3k$ maybe. We do have a working AF5x with a 34dbi dish doing 150Mbps aggregate. The link gets bad sometimes because of ducting/reflection. How could I use two parabolics dish on different polarity with the AF5x for space diversity? Splitter? Should a B5C perform better or worse ? Charles
