Finally: A Real Solution to Remote-Site Communication Problems
If you're a security company managing large teams across remote job sites, infrastructure zones, or high-risk areas, then you know the pain: inconsistent comms, limited range, dropped signals, and overpriced "solutions" that underdeliver.
The LC-689 changes the equation.
This 50-watt tri-band repeater and mobile radio was built to solve the most critical issue for field teams: reliable, long-range, multi-channel communication—without delay, interference, or dead zones.
And now for the feature that sets it apart from nearly everything else on the market:
Turn Any Vehicle Into a Mobile Repeater Station
Operators using handheld radios within range of a vehicle equipped with the LC-689 can have their transmissions automatically re-broadcast at 50 watts using the truck’s mounted antenna—massively extending their range without upgrading their handheld gear.
This unique feature:
Increases handheld comms range dramatically
Enables field teams to reach HQ or remote units via one mobile relay point
Removes the need for large, fixed repeater towers or multiple base stations
This is an extremely rare capability at a fraction of the cost and complexity of mesh network systems.
