Since none of the AC client radios are 4x4 what does the 3000 do with the other two chains besides MU ?
I even seen a post were someone connected a 3000 to 2 RF-Elements 90° horns pointing 90° from each other and Cambium chimed in and said this would work. So all of the AC/N radios connecting to that 3000 would only be using 2 chains from whichever horn they were connecting to.
So given that, if they never had any customer radios connect to the 2nd horn, then they have no MU happening (since that would required AC radios on each horn to take advantage of MU) and the effect would be the same as having only Ch0 and CH1 connected since the horn connected to CH2 and CH3 is doing nothing, correct ?
