HX446E

Overview Features Accessories Technical Specification

The first time you handle our HX446E you will be impressed by its superior build quality. From the compact ergonomic design that fits comfortably in your hand, to the exceptionally loud audio that enables you to communicate in the noisiest environments, this radio, positioned as an entry level PMR446 model, easily outclasses its competition.

For your convenience the HX446E has a 16 channel capacity, allowing you to duplicate all 8 European PMR446 allocated channels on a different CTCSS or DCS tone. Alternatively, just use the first 8 positions.

This PMR446 model, like all our HX series 2.0 portables, meets the MIL-STD 810C/D/E/F rating for tough enduring performance and in addition has a superior IP55 splash proof construction. Utilising the latest intelligent Lithium-Ion battery technology with battery cycle count* your HX446E will even alert you to imminent battery life expiration.

The HX446E comes with channel scanning, VOX and local personal attack alarm, with optional Bluetooth communications facility and variable point voice scrambler. This low cost entry level model will exceed the expectations of even the most experienced radio users.

*Battery cycle count can only be displayed on LCD model.
