CM Dipole in free space, converted with 4nec2 on 29-Mar-06 22:08
CM 	Dipole1
CM This is a plain dipole in free space, about the simplest
CM antenna you're likely to model. 
CM The frequency is 299.7+ MHz, at which a wavelength is one
CM meter. The antenna dimensions, in meters, are therefore 
CM also the dimensions in wavelengths. Note that this antenna,
CM exactly a half wavelength long, is greater than a resonant
CM length, as indicated by the positive feedpoint reactance.
CM A resonant "half-wave" antenna is somewhat shorter than 0.5
CM wavelength, the amount depending on its diameter.
