Why 4G LTE Two-Way Radios?
Unlimited Range
Talk across any distance with cellular coverage — no repeaters needed.
All-Day Battery
Large-capacity batteries keep your team connected through full shifts.
Group & Private Calls
Reach one person or your entire team instantly with a single press.
Built Tough
Water-resistant and drop-tested for real working conditions.
5,000 km Range.
Zero Dead Zones.
The Model 280 runs on 4G LTE for unlimited push-to-talk, and falls back to 2W UHF/VHF analog when data isn't available. One device. Both worlds.
Dual-Mode.
One Radio.
Most network radios lock you into 4G-only. The 280 gives you both — switch between 4G LTE PoC and 2W analog UHF/VHF. Use digital when range matters, analog when infrastructure doesn't exist.

2W Analog UHF/VHF
Fallback on UHF 400–470 MHz or VHF 136–174 MHz. 16 channels. Works without SIM or data.
Automatic Network Switching
Linux OS manages seamless handover so you're never caught mid-transmission.
