     Entel HX420

 

 

Half the size of most of its competition the HX420 Series is one of the smallest radios in Europe. Weighing just 274g the HX420 is small enough to slip into any pocket with ease.

The HX420 delivers a full 5 watts of RF - the maximum power available on the licensed band. This versatile model allows you to use different power levels per channel, to a minimum of 1 watt for those users requiring less range, and extended battery duration.

Designed to offer tough and enduring performance as would be expected from a commercial grade radio. The HX420 exceeds MIL-STD810C,D,E standards for shock, temprature and vibration. The HX420 is also rated to IP55 for water ingress (safe from low pressure water jets from all directions) i.e. rain proof, ensuring years of trouble free use.

The very latest battery technology gives you three big advantages:
1. Huge eleven hour duty cycle with supplied CNB400E battery pack.
2. Not prone to the dreaded memory effect that Nicad and Ni-MH battery packs suffer from, therefore no more need to fully discharge your battery pack before charging!
3. Stores a charge up to three times longer than a Nicad
