Why is the SR5 showing low output power below 5475Mhz?

The SR5 only exhibits hi-power from 5475MHz-5825MHz. Power has been configured to drop off dramatically at frequencies below 5475MHz to discourage illegal hi-power operation in these bands.

   
What is the antenna port configuration on the SR5 and SR2?
Antenna B (port 2) is the MMCX / Antenna A (port 1) is the u.fl connector.
   
What is the performance difference between the u.fl and MMCX connectors on the SR5 and SR2?
Assuring the cable quality is good, like the ones demarc uses and sells, using the u.Fl connector has been found to produce slightly superior performance results in both SR2 and SR5. From our lab tests using the cables we sell and use in our prodcuts the u.fl has 1 to 1.5dBm better performance on the SR5, the SR2 is less then .5dBm
