A coaxial cable has an attenuation of 3.5 dB per 100 ft at 100 MHz.
a. What is the attenuation of 60 ft of cable?
b. How is attenuation affected if the frequency is raised to 300 MHz?

a. Attenuation per foot is 3.5/100 = 0.035 dB/ft, so attenuation for 60 ft is 0.35 \times 60 = 2.1 dB.
b. The same cable used at 300 MHz would have significantly higher attenuation
