same signal would if transmitted on the 70 centimeter band. The reader is advised to note that receiver front-end noise figure and antenna gain are the defining factors in line-of-sight signal propagation in the local area. The 33 centimeter band offers excellent building penetration characteristics since the wavelength is relatively small and can fit through windows more easily than signals lower in frequency. In many areas, the 33 centimeter band also has a very low noise floor as compared to bands lower in frequency .
