The Zartek ZA-748 Portable Two Way Radio is easy to use and gives you reliable and clear communication. The ZA-748 UHF transceiver operates at 0.5 W on both license-free bands, namely 464 MHz consisting of 5 frequencies and 446 MHz consisting of 8 frequencies. This transceiver is also approved by ICASA to operate on licensed bands from 400-470 MHz on 2W of transmitting power.
High strength materials and quality components have been used in the manufacture of this two-way radio to give many years of product use. It is designed for rugged outdoor and industrial use to excel in tough environments. The ZA-748 radio is ultra small and compact for easy handling. Li-ion battery technology and VOX (voice activation) are included amongst many features that enhance performance yet keep the transceiver easy to operate. A detachable antenna enables external car or house antennas to be used with the radio to extend communication range.
