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.

Features

Submersible to IP68 (5 metres for 1 hour)play

Entel is the first manufacturer to offer the superior IP68 specification, whereby we ourselves determine at what depth and for how long our equipment must remain waterproof. Not content with just the standard IP67 entry-level (1 metre for 30 minutes) Entel's IP68 HT series is certified as waterproof-submersible to an unprecedented depth of 5 metres for 60 minutes.

Aware that the smallest tolerances of case size and material variation alone could compromise your radio's waterproof integrity, uniquely, each individual Entel portable is tested on a custom-built air pressure test-jig to ensure it meets the exacting high standards we have set for ourselves.

MILSTD 810C/D/E/Fplay

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.

play

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 socketmore

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.
