• The Booster supports monitoring of DC Donor antennas. This requires a DC path through the
transmission line (and lightning protector) to the donor antenna. If the donor antenna doesn’t provide
a DC return path, install a 1dB attenuator at the Donor antenna as illustrated in Figure
2-1.
NOTE: A 1dB attenuator is provided in the packing list. Use the same type of attenuator for the Donor
antenna (if it does not provide a DC return path). If used on an antenna installed outdoors, be sure provide
suitable weatherproofing over attenuator and connectors or fit inside building.
