Use these calculators to perform additional link budget calculations. The Rain Rate to Attenuation calculator allows you to view attenuation by channel for a given rain rate. The Signal Budget to Rain Rate calculator allows you to calculate the max rain rate a link with the given budget and distance can handle before it drops, provided for each channel.
