Statement - 1: Sky state of signals are used for long distance radio communication. These signals are in general, less stable than ground wave signals.
Statement -2: The state of ionosphere varies from hour to hour, day to day and seasons to seasons.

2.
What are the components in a communication channel?

3.
When speaking of antennas. ______ is a section which would be a complete antenna by itself.​

Answer 1

3.Bay

Reason- Bay section of the antenna has it ,it has all the components that built an antenna ,that's why it is an antenna by itself.
