Studying for Basic Test (Canada)

[shifty21]

Working through some of the test questions. B-006-12-01 has got me stumped. I see half wave length therefore 150 / 28.550, but that's not the answer. How's this one figured out?

Thanks in advance.

The frequency in question is in the 10 meter band. Half of 10 meters is 5 meters.

I'd say 5.08 meters is the most correct answer.

In feet, the length of a half-wave antenna is 468/f. So, 468/28.55 is 16.4 feet...not accounting for the velocity factor of the wire.

The correct answer as per Industry Canada is 10.16. The correct answer is always in brackets. That's where I was scratching my head.
