Product description

Tough enough for even the most extreme environments

The Entel HT446L is an IP68 fully submersible license free radio with a high visibility LCD display, which has been designed for even the most hostile environments.

One of the toughest on the market

This Entel radio is the only two way radio that has been certified with the unprecedented IP68 rating - withstanding submersion to a depth of 5 metres for 60 minutes. Each radio is tested individually to ensure it meets these high standards. It also guarantees optimum perfomance while withstanding shock, vibrations, and corrosion from dust and moisture. Its accessory socket is also protected with a shearing point and is designed to withstand rough use.

Feel assured by high testing standards

This cost effective radio has been designed for use in extreme environments, with the same mechanical construction and testing procedures as the walkie talkies used by the UK Fire and Rescue services and petrochemical companies. It also meets the stringent Mil-Std 810C/D/E/F standards, regarding perfomance with shock, vibrations, and corrosion from dust and moisture.

Never get drowned out with loud audio

With extra loud audio, this radio is ideal for use in noisy environments and can be used hands free with a VOX-enabled audio accessory.

LCD screen and intelligent battery technology

The high visibility backlit LCD screen displays the 8 PMR446 channels, which can be expanded to 255 with different CTCSS or DCS tones. Its intelligent Lithium-Ion battery technology, which alerts users to immiment battery life expiration and maximises duty cycles, is also designed to withstand heavy duty use.

The HX446E comes with optional features such as channel scan, and a personal attack alarm, Bluetooth and voice scrambler. It can also be upgraded with new features via Flash Upgrade technology and data from one radio can easily be cloned to another.

Important: the range of a PMR446 radio varies a lot depending on where you use it. The maximum range given by manufacturers is based on ideal conditions, such as from hilltop to hilltop, but the range you actually get will be much less if you are in a built-up area. Trees, walls, hills and even the weather can affect the range of your radio.
