Antenna Cabling and Power Verification
4 Connect the antenna cable from the TRX port that you are testing to the “out”
port of the RF watt meter. See Figure 5-4.
5 Connect the RF cable between the Micro BTS RF output port (antenna
connector) and the RF watt meter, as shown in Figure 5-4. This is the recom-
mended method of testing forward and reflected power. Typical test cable loss
is listed in Table 5-3.
