396. If a transmission line has a power loss of 6 dB per 100 feet, what is the power at the feed point to the antenna at the end of a 200 foot transmission line fed by a 100 watt transmitter?
A 200-foot transmission line with a 6 dB loss per 100 feet results in a total 12 dB loss, reducing the power from a 100-watt transmitter to approximately 6 watts.
