Question B-006-011-004

Approximately how long is the reflector element of a Yagi antenna for 28.1 MHz?

Correct Answer

5.33 metres (17.5 feet)

Explanation

Reflectors are longer than the driven element. Half-wavelength at 28.1 MHz ≈ 150/28.1 ≈ 5.34m or 468/28.1 ≈ 16.6 ft. Reflectors are typically 5% longer. 5.33m / 17.5 ft seems slightly long, but plausible as reflector length.
