(F)Element 8-49 Installation Flashcards
1
Q
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.
2
Q
RADAR interference to a communications receiver is eliminated by:
A
Properly grounding, bonding, and shielding all units.
3
Q
Why should long horizontal runs of waveguide be avoided?
A
To prevent accumulation of condensation.
4
Q
Long horizontal sections of waveguides are not desirable because:
A
Moisture can accumulate in the waveguide.
5
Q
In a RADAR system, waveguides should be installed:
A
As straight as possible to reduce distortion.
6
Q
What is the most important factor to consider in locating the antenna?
A
The antenna is in a location that is not shadowed by other structures.
