*The typical coupling value for the supported bands is -26 dB however a delta of +/- 3 dB can be expected. As such, the actual coupling value for each unit
(measured for the DL center frequency of supported bands) is specified on a label on the unit. Note that the test port is bi-directional, so that an UL signal
can also be injected and measured with a -26 dB loss.
