Well, I would like to test one. I have the earlier 036H unit and use it often.
...Looks like it does have higher power but hard to tell the exact comparison since the specs are apples and oranges (different conditions).
...More important is the sensitivity...which measures the receiver capability. It does no good to increase the Tx power if you can not "see" or hear the AP.
On sensitivity, it looks about the same....so, not a clear benefit. On my 036H, once I "see" an AP on airodump-ng I can usually bump up the Tx power to connect.
...The capability to set the Tx power on the Alfa exists on kernels < 2.6.31 but was lost on the 2.6.31. So, dependent on the kernel used in BT, you may or may not have TX power setting capability.
...Yes, the higher the TX Power...the higher the health risk. Separate yourself from the antenna....since power decreases by the inverse of the distance squared.
...Actual power transmitted depends on many things (loss of cable and antenna as well as the Tx from the unit.....which depends on the notes above).
