(**) You would require to use a pair of ATW-SC410 to connect 2 pairs of antennas. Please use the above table to determine the maximum numbers of active componets in the antenna cable run.
Polarization
Vertical (when mounted vertically)
Example: AT-One (100 mA per antenna cable run) could drive 1 pair of ATW-B80WB boosters and 1 pair of ATW-SC410 splitter. (60 mA + 0 mA = 60 mA). Example: ATW-DA49a (250 mA per antenna cable run) could drive 2 pairs of ATW-A49a (0 mA), 2 pairs of ATW-B80WB boosters (2x 60mA per antenna run) and 1 pair of ATW-SC410 (0 mA): Total 2x 120 mA.
