Entel HT446E

For those requiring an entry level PMR446 portable with a no compromise build specification, the HT446E is the most cost effective solution. From an established generation of commercial grade portables, the fully submersible IP68 HT Series 2.0 is designed to operate in the most hostile environments and with its MIL-STD 810C/D/E/F construction and exceptionally loud audio, is the choice of the fire & rescue services and major blue-chip petrochem organisations worldwide.

For your convenience the HT446E 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. Utilising the latest intelligent Lithium-Ion battery technology with battery cycle count* your HT446E will even alert you to imminent battery life expiration.

The HT446E 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.
