HANDHELDS LOSE RANGE.
CELL SERVICE FAILS.
WORKERS GET SPREAD OUT.
TRUCKS BECOME THE ONLY RELIABLE LINK.
THIS FIXES THAT.
 
The HT-689 turns a properly equipped vehicle into a 50-watt
mobile repeater station.
Your handheld radios no longer have to do all the work.
They transmit to the vehicle.
The vehicle rebroadcasts the signal.
Your crew gets stronger site-wide communication.
 
WHY IT MATTERS
• Turns a vehicle into a mobile repeater hub
• Extends handheld radio coverage across larger work areas
• Rebroadcasts compatible handheld transmissions at up to 50W
• Helps connect crews working outside normal handheld range
• Built for remote sites, yards, access roads, facilities,
field crews, patrol units, and mobile operations
• Reduces dependence on cell service
• Reduces the need for fixed repeater towers on temporary
or changing sites
• Gives supervisors, operators, and lone workers a stronger
communication backbone
 
THE SIMPLE VERSION
One vehicle.
One mounted radio.
One proper antenna.
A much stronger communication footprint.
