That's because airfibers use a fixed up/down ratio (75/25, in this case). If you needed 50/50, this link would only be get you somewhere around 140Mbps each way. Signal is just a little too low to get 8X (256qam) on this case, but I probably could if I changed them to the new HD version, since they can get a little higher power at any given modulation, and they can achieve higher modulations at lower signal levels... it might even be able to do 1024qam (it probably could with 3' dishes anyway). going to a 50mhz channel would also add some 20% capacity (50mhz is the max for the standard af-5x, but the hd can go up to 100mhz if you have lots of spectrum to burn).
An entire link with 2' dishes should come to router around $1000. I haven't priced the 3' dishes recently, but they are quite a bit pricier.
