Welcome to the Fun-antennas-01 quiz.
This is a 'fun' quiz meaning it is intended to both refresh your memory and to a limited degree, prepare you for the Ham Tournament Equinox series.
Note that there are 10 questions.
There are two parallel grading schemes as follows.
Difficulty Points Grading
Some answers are worth more than one point to account for difficulty. Some questions may have two or more correct answers (marked as such) with each answer worth either one point, or a different number of points, again, based on difficulty.
Correct / Incorrect Grading
Each answer, whether it be worth one point or more points, is marked as correct or incorrect. The total number of correct answers is marked out of the possible maximum number of correct answers. So if there was only one question in the quiz and that question had two possible correct answers, if you chose only one of them, you would score 1 out of 2.

1.
Which of these does not manufacture or sell HF antennas?
2.
Why does the reactance of a coil increase as it is placed farther from the feedpoint of an antenna?
3.
When soldering wire, what is the best practice to ensure a solid and reliable connection?
4.
What is the main purpose of an antenna tuner?
5.
Which of these is not usually considered a rotator rating?
6.
In the United States, the National Electrical Code (NEC) specifies the minimum required conductor size (in American Wire Gauge, AWG) for hard-drawn copper wire used in unsupported spans between two supports. For an unsupported span of 150 feet, what is the minimum AWG size required for safety and structural integrity?
7.
In antenna design, what is the Q value?
8.
Elliptical polarization
9.
Radiation directly downward from an antenna reflects vertically from the ground then, as it passes back upwards through the antenna, induces a current in it.
10.
What would this azimuthal pattern likely represent?
Pick up to three answers. The best answer, representing this actual antenna, is worth two points. The other two possible choices are each worth one point.
