Introduction
Photograph of NT-LB series radio transceiver

High specifications standards, Excellent cost effectiveness, Greater flexibilities in design for future expansion in radio systems.

These are what our NT-LB series are all about.

The NT-LB exceeds European CEPT standards in all parameters, at the excellent cost efficiency. Flexibility is another excellence of the NT-LB. The radios are accessible to any types of additional functions which include 5 tone, 2 tone, CTCSS, DTMF, ANI of selective calling as well as Scanings, Priority channel or Custom designed sub-assemblies. To facilitate those additional functions, two optional versions are offered with special displays and auxiliary switches.

Those excellences are inherent in the NT-LB series of the 66-88, 134-174, 215-245, 300-350, and 400-512MHz, spectrums.

The NT-LB is the right and best answer to your needs today and for tomorrow with the excellences in the flexibilities.
