Send Inquiry
The NT-LB series, a compact, robust dashboard mountable mobile for FM operation gives you a choice of up to 16 synthesized channels which can be programmed. Its compact design and superior sensitivity makes it a fixed station when it is used with mains power supply and external antenna. Its power output is adjustable from 10W to 30W. The facilities it offers include CTCSS/Selcall with 5 tone, DTMF, 2 tone. Models are available to cover the 68-88/134-174/215-245/300-350 and 400-512 MHz bands.
