1-6. RG-19/U is used at 100 MHz with an input power of 10 mW. The receiver sensitivity is 1 uW. Compute the maxi-mum length of the communications link.Repeat if a fiber with loss of 5 dB/km replaces the coaxial cable. The fiber system's input power and receiver sensitivity are the same as those of the.coaxial cable system.
