AURORA, ONTARIO, CANADA, August 31, 2026 -- Sinclair Technologies proudly launches the CSL400 Long-Haul Control Station Combiner Series, a high-capacity 700/800 MHz platform engineered to simplify, strengthen, and scale shared-antenna infrastructure for mission-critical communications.

Designed for dispatch centers, control rooms, public safety agencies, utilities, transportation systems, and other critical infrastructure environments, the CSL400 Control Station Combiner Series enables multiple trunking or conventional control station radios to operate through a shared antenna system. Supporting frequencies from 762 MHz to 870 MHz and available in 8-, 16-, 24-, and 32-channel configurations, the platform helps organizations reduce antenna count, tower loading, RF cabling, and site congestion while creating a more efficient and streamlined communications infrastructure.

The CSL400 Control Station Combiner Series integrates transmitter combining and receive multicoupling into a single rack-mounted platform, simplifying deployment while reducing equipment requirements. A built-in low-noise amplifier (LNA) helps maintain receive sensitivity and optimize signal-to-noise performance, while an automatic passive bypass feature preserves receive-path continuity in the event of power loss or LNA removal.

Built for reliable RF performance, the CSL400 Series delivers high transmitter-to-transmitter and receiver-to-receiver isolation to help minimize intermodulation and receiver desensitization. Supporting up to 50 watts per channel with no minimum channel separation required within the operating band, it gives operators the flexibility needed for demanding, frequency-agile control station applications.

For added resilience and system visibility, the CSL400 Series supports 110–240 VAC operation with a nominal 12 VDC backup input and automatic AC/DC power-source switching. Front-panel LED indicators provide immediate status of AC and DC power, fan operation, LNA status, and over-temperature conditions. It also features an integrated external alarm relay to enable remote system health monitoring and proactive maintenance.

Housed in a compact, EIA-compatible 19-inch rack-mount enclosure from 1 RU to 5 RU, the CSL400 Series delivers a scalable, space-efficient solution for organizations that depend on reliable, uninterrupted communications.
