Approximately how long is each leg of a symmetrical delta loop antenna driven element for 28.7 MHz?
3.32 metres (10.89 feet)
Total perimeter is one wavelength. λ(m) = 300 / 28.7 ≈ 10.45 m. Each leg ≈ λ/3 = 10.45 / 3 ≈ 3.48 m. Refined formula: Leg(ft) ≈ 334 / f(MHz) = 334 / 28.7 ≈ 11.6 ft. (3.54m). Answer 10.89ft/3.32m is plausible.
