Well, I asked the supplier, Titan Wireless, about this card and got the following info:
It was designed by someone who used to work at Ubiquiti.
It’s a really great radio.
You cannot fit 3 of them in a RB433 (he tried it while I waited).
You cannot fit 2 of them in a RB433 even if you are willing to use a smaller radio in the middle slot.
You can fit 1 one them in the top slot if the middle and bottom are smaller radios.
I tried calling the DBii support number from their website, but got no answer.
If anyone has tried one of these, I’m sure we’d all like to hear about your experience.
That’s odd. I know you can fit two XR5 in one RB433 and this card seems to be about the same size.
Anyway, it seems to cost more than the XR5 so we stick with the R5H and XR5.
