Does anyone know of any proven 3x3 MIMO 5GHz antennas? Ideally for PtP links
hit your search engine and find some on the market. But "proven", I presume that is to find out by yourself. Because the performance of any antenna system is a product of the used technology, spectrum, spectral circumstances (interferences, obstructions, fresnell), usage etc. etc. etc.
What might work for one is totally un-acceptable for another.
I made myself a 12km triple chain link with 2x2 Jirious dome and one diagonal mesh antenna on top, but probably due to interferences and/or reflection of a chimney can't get no more than about 120Mb aggregated tcp traffic over the link. I can switch on or off one chain (any chain) without loosing any throughput, so obviously something is wrong...
I am planning some new links for high throughputs so I am definitely going to use these new boards and thinking of what antenna's exactly to use.
But the main thing in mho is that you need better than 25dBi antennas to get good performances on medium to long backhauls (+10km) in 'noisy' spectrum. Since I haven't found any triple chain dish antenna (yet?) I have to play with an extra antenna.
It might be that 802.11ac dual chain setups might bypass my high bandwidth demand wishes even before good high gain triple chain antenna's will hit the market....
So Normis, next newsletter with some info on ac? (Higher power needed than the present available range of radio's.)
Why not this 952GS-5Hnt delivered with 802.11ac? That would shake the competition!
And make me happy!!!
