Installation Prerequisite: We have passed FCC certification of our system with following antennas. We strongly suggest that you should use the same antenna to avoid unexpected problems occurred in the operation. Model Number. KBNT5822-16 KBNT5828-25 Frequency 5725~5875MHz 5725~5875MHz Gain(dBi) 22 28.5 Type Panel Solid Dish Polarization Horizontal, vertical Horizontal, vertical Beamwidth Hor. VSWR Ver. Љ1.4 Љ1.15 Dimensions(mm) 350*350*37,1.2kg ĭ60cm Connector N-male N-type Step1: Mount your antenna and ODU in the appropriate position. The correct position depends on your needs. You should also take the distance between antenna and ODU into consideration. The distance is larger, then you need a longer cable to connect which usually stands for higher cable loss. Step2: Turn off you power of the system. Step3: Correctly connect your cable between ODU and antenna. Step4: Turn on the power of the system with SSPA function off. Try to adjust antenna angle by checking the LED light number or RSSI voltage to achieve the best performance. This step would decrease the power to the minimum level so that it won’t harm the installer. Step5: When best performance is achieved, then turn on the SSPA function to make the transmission better to avoid air interference or weather attenuation. Then the antenna installation is completed. 9-20 E1 Spread Spectrum Radios 9.8 RSL and Link Budget The received signal level (RSL) can be estimated using the following formula: RSL (dBm) = Pout – FL1 + G1 + G2 – FL2 – LP where: Pout is the transmitter output power (in dBm) FL1 is the feeder loss of the transmit side (in dBm) G1 is the gain of the transmit antenna (in dB) G2 is the gain of the receive antenna (in dB) FL2 is the feeder loss of the receive side (in dB) LP is the Path loss, defined by: LP (dB) = 96.6 + 20 log10F + 20 log10D where: F = Frequency in GHz (1.5, 2.4 or 5.8) D = Distance of path in km This link budget is very important for determining any potential problems during installation. If you have calculated the expected RSL, you can see if it has been achieved during installation, and troubleshoot if necessary. Figure 9-8 RSL and Link Budget 9-21
