HT ATIS Marine LCD - VHF

Overview Features Accessories Technical Specification

Superseding the multi award-winning HT series 1.0 was a challenging task, considering its success with the UK Fire & Rescue Services, major blue-chip organisations, as well as petro-chem and shipping companies worldwide. However, the new HT Series 2.0 marine portables have managed to build upon this success.

The latest Series 2.0 product to be launched is Entel’s HT644 ATIS hand portables, for use when navigating inland waterways in mainland Europe. On ATIS models, an FFSK data signal is sent at the end of each transmission, which carries information about the vessel, including a call sign unique to the craft allowing it to be tracked and monitored for safety purposes.

Like Entel’s other Series 2.0 VHF, UHF and GMDSS marine radios, these commercial grade portables, with their exceptionally loud audio and powerful Lithium-Ion batteries ensuring duty cycles of 14 hours from a single charge, are designed to withstand the everyday rigours of marine environments. Their superior MIL-STD 810/C/D/E&F commercial grade construction, together with their unique IP68 submersibility (5 metres depth for 1 hour), make them the most robust and durable marine portables available on the market.

Overview Features Accessories Technical Specification

Submersible to IP68 (5 metres for 1 hour)

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/F

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.

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.

All INT, USA and CAN channels

The HTx44 and HTx49 models are supplied preprogrammed with all INT, USA and CAN channels.

Private channels

An almost unlimited number of private channels can be programmed into the radio. These are in addition to the USA/INT/CAN channels pre-programmed.

Robust accessory socket

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.

LCD display

LCD display variants offer more information and versatility. For example, the entry level with LCD will display channel names, battery charge count, receive signal strength indicator etc.

7–key keypad

The 7–key keypad gives you direct access to functions such as channel scanning, weather channels and channel 16.

Clone data from one radio to another

Allows you to easily configure another radio to match your system.

Low battery warning

When you do eventually use almost all the charge in your battery your radio will conveniently let you know it is time to change or recharge your battery.

VOX hands free (with audio accessory)

When you attach a VOX enabled audio accessory you can operate totally hands free. All you need to do is talk and your Entel radio will automatically transmit for you.
