Well since the Schumann Resonance is approximately 7.83 at it's first fundamental the wavelength is approximately 38287671 Meters. A Quarter Wavelength Antenna would be 9572 Meters Long. But making it useable size would be to use a 1/40th wavelength antenna which would be about 239.3 Meters "ish"
But yes any frequency can be transmitted via an antenna.
