5. One of the purposes of a(n) is to emit an electromagnetic signal into air or space. a antenna b. modulator c. filter d. mixer A transmitter generates a 15 dBm signal and is connected to an antenna using a cable that has 3 dB loss. The cable has two connectors that induce a loss of 2 dB each. What is the 6. signal level at the input of the antenna? a. 8 dBmm b. 10 dB c. 22 dBm d. 3 db 7, A(n)- antenna transmits a signal in all directions with relatively equal intensity a multidirectional b. phased array c. directional d. omnidirectional 8. Between the transmitting antenna and the receiving antenna, a signal will always be subject to a gain b. amplification c. free space loss d. reflection e. diffraction
