Use the Graph below to answer the following questions outlined below: 10 5.0 + RG-58A/U RG-8A/U (foam) RG-59/0 9913 2.0 + Loss (dB/100 ft) 1.0 H 0.5 + 0.2+ 0.1 1.0 MHz 10 MHz 100 MHz 1000 MHz (1 GHz) Frequency 1) One of the four cables shown in the graph above can be used to connect an amplifier to an antenna that is approximately 1000 ft away. An engineer selects the best cable from the options shown in the graph above. What cable was selected and explain your reasoning for selecting your answer. No credit will be given for answers without an explanation. 2) Using the cable selected in the question above, using the graph above, estimate the total loss in dB for system assuming an operating frequency of 10 MHz. Describe your steps that you took to come to your answer. 3) If the output power from the amplifier is 20W, what was the resulting output power that was seen at the antenna in dBm. Describe the steps taken to reach your answer to obtain partial or full credit, 4) If the characteristic impedance of the cable used is 50 ohms and the antenna has an equivalent mismatched load of 25 ohms, what is the reflection coefficient (gamma) of this system? What is the resulting SWR for this load?
