After Matt Tottle's post about Sprint losing roaming partners in eastern Colorado, I'm going to try load balancing today on the High Plains with a Sprint and Verizon data card. My question is this: Do you have to use 2 separate amplifiers (one for each data card with the appropriate cable), to achieve an amplified signal for both data cards when using a Cradlepoint router or is there a Y adapter of some sort so only 1 amplifier is needed? I hope this makes sense as it never occurred to me until I was playing around with it at home today before heading out this afternoon. I have a direct connect amplifier - the Rockies model.
