A transmitter generates a 15 dBm signal and is connected to an antenna using a cable that induces a 3 dB loss. The cable has two connectors that induce a loss of 2 dB each. What is the signal level at the input of the antenna?
A) 8 dBm
B) 10 dB
C) 22 dBm
D) 3 db

The initial signal is 15 dBm. Subtracting the losses (3 dB for the cable and 2 dB for each connector, totaling 7 dB), the signal level at the antenna is 15 dBm - 7 dB = 8 dBm.
