Data rate is mostly a function of equipment, not of the cable; it would be nice to know what loss-per-foot they've measured at 10 & 18 GHz, but those numbers would depend on cable suppliers and I bet they change from time to time.
Another excellent buy from Monoprice, especially when it's on sale. Good intermediate length, thin enough to bundle up pretty unnoticeably. Takes care of high speed data. All in all, another good buy from Monoprice.
