Chapter 4
1. B, D. The - and H plane plots are used to show a side view and a top-down view, respectively, with the antenna in the center of the plots.
2. B. The H plane is also known as the azimuth plane because measurements are taken at every azimuth angle around the base of the antenna.
3. D. The beamwidth is the angle measured between the two points on a radiation pattern plot that are 3 dB below the maximum.
4. D. A wave’s orientation with respect to the horizon is known as the polarization.
5. B. Cisco antennas are designed to use vertical polarization. Because the dipole antenna is mounted correctly (pointing straight up or down), the wave will be vertically polarized.
6. B. A parabolic dish antenna has the greatest gain because it focuses ...
