We measure antenna field strengths in their far field using a pair of tuned half wave dipoles. A reference measurement is taken. After replacing one of the reference dipoles we repeat the measurement process.…

What is line of sight communications? How does this work?

The transfer of energy through space is called propagation. In general, radio waves at UHF and above are Line of Sight, which means the wave travels almost like a beam of light in a straight line and thus requires that the transmitter and receiver be within sighting distance of each other. Although other factors sometimes…
