- What is the relationship between frequency and wavelength in radio waves?
- They are inversely proportional: as frequency increases, wavelength decreases. Wavelength (meters) = 300 divided by frequency (MHz).
- What does AM stand for in radio?
- Amplitude Modulation
- What does FM stand for in radio?
- Frequency Modulation
- What does SSB stand for?
- Single Sideband
- What are the frequency limits of the 2-meter amateur radio band?
- 144 MHz to 148 MHz
- What are the frequency limits of the 70-centimeter amateur radio band?
- 420 MHz to 450 MHz
- What is the maximum transmitting power allowed for a Technician class licensee on VHF/UHF bands?
- 1500 watts PEP (Peak Envelope Power) on most bands
- What does PEP stand for?
- Peak Envelope Power
- What is the purpose of a repeater in amateur radio?
- To receive a transmission on one frequency and retransmit it on another, extending the range of communication
- What is the correct procedure for accessing a repeater with an offset frequency?
- Transmit on the input frequency (lower frequency on VHF) and receive on the output frequency (higher frequency on VHF)
- What is the term for the direction toward which an antenna's radiation pattern has maximum gain?
- The antenna's direction of maximum radiation or main lobe
- What type of antenna is a Yagi?
- A directional antenna consisting of driven element, reflector, and director elements
- What is an isotropic radiator?
- A theoretical antenna that radiates equally in all directions
- What does dBi stand for?
- Decibels relative to isotropic radiator
- What is the main advantage of a half-wave dipole antenna?
- It is omnidirectional in the horizontal plane and has relatively simple construction and tuning
