A premium radio product requires years of communications equipment experience and a strict adherence to high standards in design, manufacturing and quality assurance. Kenwood facilities are proud to be internationally recognized as ISO-9001 certified and are pleased to bring "practical innovation" for the rigors of the real world by offering the TK-480 portables.

MIL-STD 810C/D/E

The TK-480 meet or exceed tough U.S. Department of Defense environmental standards in addition to Kenwood's own technical and industrial standards.

DIE-Cast Chassis

The monocoque aluminum die-cast chassis-heat sink borrows a principal from aircraft construction for rigid strength. Surrounding this and forming an integral part of the chassis, is the super-tough polycarbonate case to provide years of durability.

Weather-Sealed Universal Connector

The universal accessory connector and battery contacts use spring action gold-alloy elements for excellent contact, conductivity and anti-corrosive properties. The universal connector is designed to mate with Kenwood audio accessories such as the KMC-25 and still maintain the MIL-STD 810C, D & E.

Weather-Resistant

Elements like the polyvinyl keypad membrane and speaker cone prevent moisture penetration for confident wet weather use.

Elements of a Premium Radio Product

A premium radio design like the TK-480 portables use state-of-the art surface mount technology, multiple layer epoxy PC boards, high-level integrated circuits and hybrid components to create a symphony of compact, rugged and power efficient performance.

High Output Audio

 
The TK-480 have an extra large 1.58 inch speaker element and half watt of audio power that provides robust clarity in noisy crowds and industrial environments.

Extra-Long Battery Life

 
The KNB-16A 1100 mAh and KNB-17A 1500 mAh batteries deliver better than 8 and 10 hours life respectively on a single charge (5-5-90 duty).

World Class Performance

 
Take a look inside and compare! You'll see a culmination of over 50 years of world class design experience that gives the TK-480 their excellent receiver and transmitter characteristics making them equally at home in urban or rural environments. The high stability oscillators, efficient MOS-FET power modules and advanced filtering are only part of what give the TK-480 both the protection and power to become the key complement to any well designed radio system.
