Answer - D - Channel 13 on a video line has the greatest loss in a VHF system.

Key Takeaway: Video signal is lost as it travels through the coaxial cable. This loss is dependent on the length of the wire. The average loss is 3 dB to 6 dB per 100 feet. Signal loss also depends on the type of wire and the frequency of the signal being carried. Losses are greater at higher frequencies. The greatest loss occurs at channel 13 in a VHF system or channel 83 in a UHF/VHF system.
