✍️ Sample Ham Radio General Class Test Questions & Answers
1. What is the feed point impedance of a quarter-wave ground-plane antenna with the radials bent downward at 45 degrees?
Bending the radials of a ground-plane antenna downward to 45 degrees raises the feed point impedance to approximately 50 ohms, providing a good match to common coaxial cable.
2. What action is required if an RF exposure evaluation shows that MPE limits are exceeded at the property boundary?
Operators must take corrective action such as reducing power, raising the antenna, using a directional antenna, or reducing operating time to achieve compliance.
3. What is the primary advantage of a log-periodic dipole array (LPDA) antenna?
An LPDA provides relatively constant gain and impedance characteristics across a wide frequency range.
4. What is the highest frequency limit of the General class phone segment on 40 meters?
General class phone privileges on 40 meters run from 7.175 MHz up to 7.300 MHz, the top of the band.
5. What type of feed line loss increases significantly when the line is operated with high SWR?
Coaxial cable losses increase dramatically under high SWR conditions compared to open-wire feed lines.
6. What is the recommended minimum safe distance approach when working near an energized amateur antenna?
The safest practice is to completely de-energize the antenna system before anyone works near it to eliminate all RF exposure risk.
