b. Compare waveguide and transmission line from the point of view of frequency limitation, attenuation, spurious radiation and power handling capacity.
c. What are the typical frequencies, bandwidths and repeater gains and spacings in a coaxial cable system?
d. How do the three main types of INTELSAT satellite earth stations vary from each other, in general appearance and applications?
