Contact RL 400 series - A new generation of tactical radio relay equipment

The RL 400 series of tactical radio-relay devices, satisfying future communications capability and operational reliability requirements in high electronic countermeasures (ECM) activity combat environments, is described. Characteristics of the systems' keyboard control, order wire, and built-in scrambler elements are discussed. Because RL 400 devices can be operated at very low output power without transmission loss, intra-network interference is reduced and ECM susceptibility is minimized by preventing detection by enemy direction-finders.
