CommScope / Andrew RET actuators, controllers and splitters

ATM200 and E-ATM300 are external RET actuators that mount on the antenna; MDCU is CommScope's internal actuator family built into the antenna itself, distinguished by a motor-position suffix (G0101, G0102, G0103) rather than a separate housing. ATC200 and ATC300 are the RET controllers that sit at the base of the tower and talk to actuators over the AISG bus — ATC300 adds port isolation and extra modem ports over ATC200. Splitters are read by way count and frequency range: S-2-UW covers 2-way, S-4-UW covers 4-way, both across the 555-6000MHz ultra-wideband range; E-prefixed parts are diplexers combining two bands onto one feed.

Confirm the AISG protocol version your controller and actuators use (1.1 or 2.0/3GPP) before ordering, since a mismatch will not commission even though the connectors fit. State the antenna model the actuator mounts to if ordering an external ATM200/E-ATM300, or confirm the antenna's internal MDCU variant if replacing a built-in actuator. Condition is stated per quotation — new, new-surplus or refurbished — and where a destination does not admit used network equipment (Algeria is the usual example) we quote new. Hardware only: software licensing remains between the buyer and the manufacturer. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.

ATC300 and current MDCU actuator variants remain in production; ATM200 and ATC200 are increasingly supplied as surplus or refurbished as CommScope moves buyers to newer controller generations. Splitters and diplexers are stable, low-obsolescence parts and are sourced new or surplus interchangeably.
