8-49F1 A
Why is coaxial cable often used for S-band installations instead of a waveguide?
A. Losses can be kept reasonable at S-band frequencies and the installation cost is lower.
B. A waveguide will not support the power density required for modern S-band RADAR transmitters.
C. S-band waveguide flanges show too much leakage and are unsafe for use near personnel.
D. Dimensions for S-band waveguide do not permit a rugged enough installation for use by ships at sea.
