Wideband Communications between the RDA and RPG -
Microwave Line-of-Site (MLOS)

This type of wideband link was originally used when the distance between the Radar Data Acquisition Unit (RDA) and the Radar Product Generator (RPG) is between 0.6 and 24 miles and when Telco T1 service was not available. Three NWS sites use this connection type as a backup to their primary (Telco) wideband link.
