Handbook of Antenna Technologiesessure, weight and volume. The concept of constant total ionization per unit volume is acceptable and can be utilized to compare hydrocarbon type analysis procedures. Sources of error in several published methods are described. A revised type analysis method which is based upon the correction of min
