I'm using R52N's on a link that is 28 Miles.  Using the same Dish.  I have 
-60's on the signal, and we can do ~50MBit+ across the link.  My first guess is 
alignment.  We had XR5's on the link, and it was -50.  At that distance with 
those cards/antennas, your signal should be a little better.  Also could be a 
bad jumper.  Also, we had a few clients on the distribution side of our 
business complain that those dishes are not performing for them, but we have 
not seen any direct issue.  With MikroTik you can run NStreme and really 
optimize the link or use the new N cards and get even better performance.

We did not try that this time in the past we have had them down as low as 12 
but the signal got worse and no real improvement in speed. They are currently 
at 14.

Are you running the XR5's at full power? Have you tried dialing down the tx 
power? We had a similar issue with some dual-pol antennas and had to turn the 
tx power down to less than 14db.

Subject: [WISPA] Dual Pol FDX Link Issue

I have a 18 mile 5GHz Link to 50MB fiber connection. Original config was a 
HDDA5W-29-DP, 26 Inch 29 dBi dual pol Pacwireless dish at each end, StarOS War2 
boards with 2 XR5 using the StarOS FDX.  The link has never performed well.  
10meg x 5 was the best I could get running ½ duplex.  The Horizontal had never 
worked right or so I thought.  Recently we added another DCE and 2nd WAR board 
at each end to reduce self interference and realigned the Antennas.  We setup a 
MTIK at each end and did Pseudo FDX through them.  No better.  If we run FDX 
the Horizontal all but crashes so we set it back to 1/2 .     

Yesterday we tried something new.  We set our routing so that our inbound come 
up the Vertical of FDX link and outbound goes out a second link.  I then got 20 
Meg across the Vertical link.  I switched to the horizontal link for inbound, 
20 meg.  I switched direction outbound through the FDX link 20MB.  This was 
making no sense.  We bonded the Vert and Hor  together still going just one 
direction and the speed fell to <6MB.  Put it back to FDX reset route tables 
and with a heavy speed test and lots of customer traffic all we could get was 
3MB down 1MB up.  We have tried all types of Channels Hor is on 5825 and Vert 
is on 5240  so there is plenty of separation. Signal is -57 with a -96 floor.  
Currently I am running Inbound through the Vertical side and Outbound through 
the other path I have which all returns back to the same NOC getting me 20Mb x 
15Mb, but I don't like that setup for failover and tracert issues.  Not sure 
all my VPN clients will like it either.

So any one have any Ideas?  There has to be an issue with the Antennas I think 
but the installer has these same antennas being used else ware on spectra link 
radios and getting 100MB FDX.  I cant just change antennas, One end is on a 
CrowneCastle tower and I have to do a full new engineer fee to change anything. 
 What can I try next?
