Entel - HX446E

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.

Environmental protection to IP55

The practical HX Series 2.0 radios enjoy an IP55 rated construction, which means that they are dust protected and resistant to water ingress (i.e. splash proof). For most day to day applications, this level of protection is perfectly adequate, however, where full protection against immersion in water is required, users should consider our IP68 rated HT Series 2.0 radios.

MILSTD 810C/D/E/F

Meeting MIL-STD 810C/D/E/F commercial grade construction for tough, enduring performance, the Entel's HT and HX series 2.0 portables conform to stringent standards, enabling them to withstand the everyday rigours of shock, vibration and the corrosive effects of dust and moisture, ensuring many years of trouble free use in the most hostile environments.

1800mAh Li-Ion battery

All Entel portables come with the latest intelligent Lithium-Ion battery technology as standard. Whichever model you choose, these batteries will count the number of completed charge cycles, which on LCD variants, if dealer enabled, can be displayed when you power-on your radio.

For your convenience it will even alert you to imminent battery life expiration. Another advantage of Lithium-Ion battery technology is the way it maximizes duty cycles, while the elimination of memory effect means there is no need to fully discharge the cells before recharging. Therefore you are assured a full duty cycle each and every time you take your radio from its charger.

Flash upgradeable to add future features

Entel proposes to continuously add/upgrade features to its range of radios. Using Flash Upgrade technology your radios can be upgraded by your Dealer at any time.

Robust accessory socket

A completely redesigned accessory connector, when secured to the portable, is designed to withstand any amount of punishment from dropping to careless misuse. Furthermore, the securing bolt incorporates a shearing point to protect the connector.

Programmable channel monitor button

If you have Analogue or Digital squelch enabled all signals other than your own will be filtered out. This can be temporarily disabled enabling you to monitor any other transmissions on your channel. This button may be programmed on or off by your Dealer.

Programmable scrambler (voice inversion)

Used to encrypt your voice, protecting against casual eavesdropping.

Local Personal Attack Alarm

All HT and HX portables include a personal attack alarm option. Once activated the speaker of your radio will emit a high pitched siren as a deterrent and provides a local call for assistance.
