The thermal noise of the resistive vee dipole (RVD) has been analyzed using a numerical model based on the method of moments. The RVD analyzed in this paper has curved arms and is loaded with surface-mount chip resistors, which approximate a modified Wu-King profile. The total noise power delivered to a 200Ω feed line and the contribution of individual resistors to the total noise power are presented. The results show that the noise temperature of the RVD is very high and the resistors close to the drive point contribute more to the total noise power than do the resistors close to the open ends of the antenna arms.
