    Product description

    Small and light enough to be lapel-worn, the SC21 is a next-generation, smart TETRA hand-held radio. With a wide range of functionality inherited from the ground-breaking SC20 hand-portable - yet 25% smaller - it offers all the benefits of a compact radio, with no compromise on performance.

    A powerful TETRA engine, coupled with exceptional receive sensitivity, gives the SC21 extended operational range, allowing you to keep communicating where other small handsets fail.

    Powerful TETRA engine

    The SC21 retains the Class 3 RF power of its big brother, as well as its exceptional receive sensitivity, ensuring unrivalled coverage in any like-for-like comparison and typically giving up to one extra wall of signal penetration within buildings.

    Best-in-class audio

    The directional speaker projects audio to the user's ear, providing extra clarity, and unique water-porting technology expels liquid and ensures that clarity is maintained even in torrential rain.

    The largest screen on any TETRA radio

    The 2.4" high resolution QVGA screen allows for quick and easy viewing in all light conditions, including direct sunlight. Night mode reduces glare in low light, and the large screen area is ideal for data-rich apps usage.

    Ergonomic keypad

    Well-spaced, hard-capped keys with haptic response allow for comfortable, accurate data entry, even with gloved hands.
