INSTALLATION GUIDE FOR RX-7W22, II2 The rated output power of this equipment is for single carrier operation. For situation when multiple carrier signals are present, the rating would have to be reduced by 3.5dB, especially where the output signal is reradiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.

INSTALLATION GUIDE FOR RX-7W22, II2 7 APPENDICES 7.1 APPENDIX A: Antenna installation: Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on permanent structures. The FCC regulations mandate that the ERP of type B signal boosters should not exceed 5W, this is equivalent to 8.2W EIRP (39.1dBm).
INSTALLATION GUIDE FOR RX-7W22, II2 For example: Out of band noise RX-7W22 PS BDA connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = 12dB Assuming 10 service antennas: antenna splitter losses = 10 dB Based on equation (2) Input antenna noise (to the antenna) = – 49.8 – 12 – 11= – 72.
