I'm looking at putting into place a dual radio link, Each Radio Set would be using a dual polarity antenna and 2x R52n cards to create a Full Duplex Link, Then have a load balance between the 2 Full Duplex links.

I'm considering using all mikrotik gear for the links, Perhaps even Ubiquiti.

I've attached a mockup of the link i'm considering using, The only difference i've been considering RB493's instead of the RB800's and then using VRRP instead of the RB750g for the load balancing. I'm not 100% sure VRRP will do load balancing correctly in this situation.

Has Anyone got any thoughts.

For those who will ask, It's a 1.6km link and there will be great LOS once the new mast goes up.

Anyone have any thoughts on this design?

I was planning on using the RB750's for some QOS filtering and priority.

Is this even slightly efficient or am I wasting my time?

Hello and welcome to the Mikrotik Forums!

Sorry for the delay in response....we're all very busy

From the looks of your design it appears that you want the fastest most realiable link possible. With that in mind here are a few things to think about.

You only need one card per RB800. The R52N card is a MIMO card. It has antenna connections for two chains (HT0 and HT1). You'll connect one plane (Horz or Vertical) to each chain. Make sure you connect them the same on both sides.

One RB800 on each side could handle the QOS filtering and VRRP setup without much trouble. It has the same processor as the RB1100 but with 256MB of RAM (512 on the RB1100).

I can understand needing two for redundancy...just know that you're going to have plenty of power to spare.

It's worth thinking about the SXT devices....you could use two of those on each side with a 750G for QOS and VRRP.

Hope that helps!
