Genuine accessories for the Sepura SC21 TETRA portable radio — a current-generation handportable used across UK and international emergency services, public safety, and critical infrastructure. The SC21 is the successor to the SC20, sharing many accessories while introducing its own form-specific parts.

Our SC21 accessories include headsets, batteries, chargers, and remote speaker microphones (RSMs) — many of which are also compatible with the SC20. The Klick Fast stud, cases, and charger insert are SC21-specific and should be selected carefully to ensure the correct fit.

The SC21 series is available across the following frequency bands:

• SC2120 — 380 to 430 MHz
• SC2124 — 403 to 470 MHz
• SC2128 — 806 to 870 MHz

If the accessory you need isn't listed, get in touch — as an authorised Sepura reseller we can advise on compatibility across the SC20, SC21, and SC23 range.
