c = λ × f λ = c / f = c × T f = c / λ
Wave frequency in Hz = 1/s and wavelength in nm = 10−9 m
frequency = f and wavelength λ

A 7.43 Hz wave is 40348917.63122477 meters (132378338.68512061 feet) in length.
This means that the length of wire to construct a quarter wave antenna would have to measure 10087229.4078061925 meters (33094584.6712801525 feet) 6267.91 miles in length.
