This is a normal diplexer. You loose 3db for 2way and 6db for 4way + 0,5-1 additional db.
The Airfibers have to be GPS-Synced and work at the same up/down ratio. ----- GENIAS INTERNET -- <http://www.genias.net> www.genias.net ------ Stefan Englhardt Email: <mailto:s...@genias.net> s...@genias.net Dr. Gesslerstr. 20 D-93051 Regensburg Tel: +49 941 942798-0 Fax: +49 941 942798-9 Von: Af [mailto:af-boun...@afmug.com] Im Auftrag von Charles Regan Gesendet: Dienstag, 1.

How many DB loss from the multiplexer? On Oct 31, 2016 11:11 PM, "Jeremy" <jeremysmi...@gmail.com <mailto:jeremysmi...@gmail.com> > wrote: If you are already using AF5X, would this be a possibility?

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.

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...

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
