Environmental protection to IP68
The practical HT446 Series 2.0 portables enjoy an IP68 (2 Meters for 4 hours) rated construction, which means that they are dust protected and fully Submersible.

Meeting MIL-STD 810C/D/E/F and providing commercial grade construction for tough, enduring performance. Entel's HT446 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.

2200mAh Li-ion battery
HT446 Series 2.0 portables are supplied with the latest intelligent Lithium-ion battery technology as standard. One key advantage of Lithium-ion battery technology is the way it eliminates ‘memory effect’ meaning there is no need to fully discharge your battery before recharging. Therefore you are assured a full charge each and every time you take your Entel battery from its charger.

Flash upgradeable to add future features
Entel adds and improves features on its HT446 radios by way of software updates. Using Flash Upgrade technology your Entel HT446 radios can be upgraded by your Dealer at any time.

Robust accessory socket
When an accessory is secured to the portable, the plug / socket has been designed to withstand any amount of punishment from dropping to careless misuse.

All non-display HT446 portables provide 16 programmable license free channels. Display portables provide 255 programmable license free channels.


To avoid accidental operation your radios keys & controls can be locked by the user or, if set, automatically by the radio.

VOX hands free (with audio accessory)
When using an Entel VOX enabled audio accessory, your HT446 portable can operate totally hands free. All you need to do is talk and the HT446 portable will automatically transmit for you.

Scan/priority scan
The HT446 Series portables have the facility to scan for an active (or free) channel. When the channel is found, the radio will automatically select it for you. Priority scan will allow you to select one channel in the scan list that is treated as a "Priority". It will be checked more frequently than all other channels in the list.

Programmable channel monitor button
If you have channel protection enabled on your HT446 portable, all signals other than your own networks will be filtered out. This can be temporarily disabled allowing you to monitor all signals on your channel.


Programmable scrambler (voice inversion)
Used to encrypt your voice, protecting against casual eavesdropping.


Local Personal Attack Alarm
All HT446 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.
