Amateur Radio Quiz: The Yagi Antenna

[ARRL]

It’s a rare ham, indeed, that has not been exposed to the Yagi antenna design at one point or another in his or her ham career. Yagis are nearly everywhere -- from fantastically large wire arrays on the HF low bands to miniature metal sculptures at UHF and up. Enjoy this quiz to find out what you know about this versatile antenna!

missed #10, i don't agree with their answer.
gain is not really a function of number of elements (yes , a slight increase does come from added elements) but, gain is mostly a function of boom length.
