	Read antex file.
void	radome2none (string &antenna_type)
	Change the last four characters of antenna type to NONE e,g, "AOAD/M_T JPLA" => "AOAD/M_T NONE" This function is useful for when searching for an antenna model in ANTEX The IGS convention is to default to NONE for the radome if the calibration value is not available.
