The values of the rain rates were calculated by using a new revised model.The obtained values of rain rates were compared with the ITU-R (International Telecommunication Union -Radio Regulations) value ascribed to Lithuania and with ones measured in the Lithuanian Weather Stations.The dependences of rain attenuation on the frequency for three locations of Biržai, Vilnius, and Kaunas have been calculated by using the values of the rain rates R obtained here and the ITU-R value.The dependence of rain attenuation on the frequency for Biržai has been calculated by using the value of rain rate obtained using Chebil's model as well.The suspicion that ITU-R value of R 0.01% is too low, described in previous paper, has been confirmed by the data presented here.
