SDR Repeater User Manual V0.4 3.5.3 Grounding Install the ground cable that has been included in the package at the back of the repeater as show in the figure below.
SDR Repeater User Manual V0.4 3.5.4 Antenna Separation/Isolation Separation between the antennas is necessary to prevent oscillation. Oscillation occurs when the signal entering the system continually reenters, due to the lack of separation between the donor and server antennas. In other words, the signal is being fed back into the system. This creates a constant amplification of the same signal. As a result, the noise level rises above the signal level.
SDR Repeater User Manual V0.4 3.5.5 Line of Sight The donor antenna which points towards the base station typically has a narrow beam antenna pattern. As a result, a slight deviation away from the direction of the BTS can lead to less than optimum results. In addition, obstacles between the repeater and the BTS may impair the repeater from obtaining any BTS signal. As a result, the repeater cannot transmit signal to the coverage area.
SDR Repeater User Manual V0.4 4. SDR Web-GUI Setup The Web-GUI allows the user to communicate with the repeater either locally or remotely. To connect to the repeater locally, you will need a laptop with an Ethernet port and a RJ-45 crossover cable. To connect to the repeater remotely, you will need to have an active internet connection and the repeater must have either an internal modem or an Omnibox (ADRF Modem Box) connected to the repeater. 4.1 Repeater/PC Connection Using Web-GUI A.

SDR Repeater User Manual V0.4 Appendix B: Shutdown Retry Logic The function of the built-in shutdown routine is to protect the repeater from any further damage from a hard-fail that the system may be experiencing. Within 5 seconds of a hard-fail alarm being detected, the repeater will start the shutdown routine. The repeater will shut down by powering of the HPAs (high-powered amplifiers) for 30 seconds.
