What is the primary purpose of an antenna?
Correct!
Wrong!
An antenna converts electrical signals into radio waves and vice versa.
What is SWR in antenna systems?
Correct!
Wrong!
SWR (Standing Wave Ratio) measures the efficiency of power transfer from the transmitter to the antenna.
What type of feedline is most commonly used for VHF antennas?
Correct!
Wrong!
Coaxial cable is the most commonly used feedline for VHF antennas.
What does impedance matching accomplish?
Correct!
Wrong!
Impedance matching ensures maximum power transfer between the transmitter and the antenna system.
Which part of the feedline can most affect performance?
Correct!
Wrong!
Feedline length, quality, and connectors all affect performance significantly.
What happens if the antenna is not resonant at the operating frequency?
Correct!
Wrong!
An unmatched antenna results in poor transmission and higher SWR.

Why is coaxial cable preferred in many amateur setups?
Correct!
Wrong!
Coax is easy to install, durable, and has good shielding properties.
What is a dipole antenna?
Correct!
Wrong!
A dipole antenna consists of two conductive elements and is resonant at its design frequency.
What could cause high SWR readings?
Correct!
Wrong!
Poor connections, mismatched impedance, or damaged feedlines often result in high SWR.
