To determine the amount of signal required to ensure a minimum of 3.0 dBmV at the television set when using 150 feet of Series 6 coaxial cable, it is essential to consider the signal loss over that cable length.

Series 6 coaxial cable typically has a signal loss of approximately 3 dB for every 100 feet. Therefore, for 150 feet, the estimated loss would be about 4.5 dB (which is derived from 3 dB for the first 100 feet and 1.5 dB for the additional 50 feet).

To achieve a final signal level of 3.0 dBmV at the TV set, you would need to add the anticipated loss to this desired output level. Consequently, 3.0 dBmV (desired signal level) plus 4.5 dB (the loss over 150 feet of cable) would require an input signal of approximately 7.5 dBmV into the cable.

However, the choices provided suggest that higher initial signal levels are necessary to account for a higher loss that comes with longer cable runs or potential additional losses from connectors and splitters. Therefore, the required level should be adjusted further for better
