Ready-to-use communication kit

This case contains ten Retevis RT21 two-way radios pre-configured on shared frequencies for immediate deployment. Each unit ships with an 1100 mAh rechargeable battery rated for up to 12 hours of operation and a two-pin acoustic tube earpiece for discreet audio. Integrated antennas and 16 channels support clear voice transmission across typical work sites. The pack includes charging bases and adapters for convenient multi-unit charging.

Suited for teams needing simple push-to-talk

Organisations such as retail floors, warehouses, hospitality venues, healthcare facilities, schools, event staff and security crews benefit from the 50 CTCSS and 208 DCS privacy codes that filter out unrelated conversations. The rugged housing, fixed antenna and belt clip withstand daily indoor and outdoor use without specialised training. Buyers requiring longer range than standard FRS limits, removable antennas, or compatibility with non-Retevis brands should evaluate other platforms.

16-channel FRS compatibility decides fit

All ten radios operate on the same 16-channel FRS layout used by Retevis H-777, H-777S, RT15, RT18, RT19, RT22 and RT68 models, allowing mixed fleets to interoperate without reprogramming. FCC certification number 2AAR8RETEVISRT21 confirms compliant transmission parameters for licence-free business use. If your existing fleet uses a different channel plan or requires UHF/GMRS frequencies outside this fixed set, these units will not communicate with it.
