Hello ,
i am not very good in english ,but i think i can help answer in question about real work of N standart.
In my city 5gh band is used allmost all posible chanels ,one radios use 5gh others 5gh-turbo and other then scaning i find about 5-8 N standart radios ,is not good for my network but all working fine
in both ends i have rb600 with full 8 slots used, 3 cards in one end use 5gh-turbo and one r52n ,in other rb600 2 cards use 5gh-tubo and one r52n.
before i use Nstrem2 to conect these 2 rb600
distance betwen them is 2.4km ,used 4 panel 23db antenas, 4x 5gh 16db wireless cards ,5gh-turbo mode ,bandwidth is about 30mbps in+out.
Now (about 1 weak) this bridge is working on N standart.

used 2 dishes 26db ,i rebuild from one polarization to V+H polarization ,2 r52n wireless cards in rb600.
optimal seetings i tested and used i find then all instaled on tower,optimal frequency is hard to find but 5210mhz is work best there.

first test before instalation
test made from PC to RB600 ,2.4km distance, RB show procesor 100% busy, one weak after instalation :

my RB600 case:

rebuid antena :

Those are a nice case, who manufactures them ?

case is from wireless AP (2.4ghz) ,manufacturer Phenet ,it have only one N type conector ,
i dril holes and instal other pigtail's ( 10 pigtail's )

you know that the speed is low?!

InoX ,yes i know that ,but because the test is made from pc to other side rb600 with all clients conected,2 eoip tunels and all wireless interfaces on , rb show about 45% procesor load ,then start test the procesor is 100% loaded , in future i do pc to pc test...

Now both antenas is aligned for best signal and performance.
heavy rain today
i made UDP test's from PC to ather end RB600 : PC----RB600>>(N wireless)>>RB600

@Real

What brand is that dish you are using?

Can you post more pics about the antenna feeder?

Please send me a personal mail I like to ask you others things too!

(i now it's an old post but i realy want to get more info about it)

Me looks like this is the dish is using in picture

@npero
Thanks for your response!

Thats exacly the antenna he is using:
brand: VOLTPLUS
model: 5542

He has modify it for dual-polarization and the model: 5524P2 is already dual-polarized.

The main problem of his modification is that the two antenna elements are too close to each other and causes interference!

Shure it wil work but not optimal.

Hello:
WOW Nice Case, looks like carrier grade!!!

Can you please post where can I get those kind cases, URL? or address.

Thanks in advance,

Joaquin

Are you not worried about cross-interference with 6 radios in one box? Maybe that is part of your noise problem.
