Entel HT783M analogue UHF Marine radio

The HT783 is designed to handle the toughest marine environments with a robust, ergonomic design that fits comfortably in your hand. Its exceptionally loud audio ensures the crew hears every call clearly, even in noisy conditions. With a market-leading IP68 submersible rating, the HT783 can endure submersion up to 2 meters for 4 hours, making it well-suited for the harsh realities of life at sea.

Versatility is a key feature of the HT700 Series 2.0. The entry models provide instant Push-To-Talk communications, while advanced models offer additional features such as individual and group calling, Lone-Worker protection, and text messaging, making this range adaptable to various communication needs.

The HT700 Series 2.0 portables come with environmental protection rated at IP68, meaning they are dustproof and fully submersible. Additionally, these radios are built to MIL-STD 810C/D/E/F standards, providing commercial-grade durability to withstand shock, vibration, and the corrosive effects of dust and moisture. This ensures reliable performance over many years, even in the most demanding environments.

Each HT700 radio is equipped with a 2200mAh Lithium-ion battery, eliminating the ‘memory effect,’ so there’s no need to fully discharge the battery before recharging. This guarantees a full charge every time you use your Entel radio, making sure it's always ready when needed.

The HT700 Series is also flash upgradeable, meaning that future features can be added through software updates, ensuring your radio stays up to date without needing a complete replacement.

The accessory socket on the HT700 Series is robustly designed to handle rough use, and the securing bolt incorporates a shearing point to protect the connector in case of accidents, ensuring long-term durability.

In terms of channels, the non-display HT700 models offer 16 programmable channels, while the display models provide up to 255 programmable channels, giving you the flexibility to manage multiple communication needs.

Convenience is built into the HT700 Series with features like keylock, which prevents accidental operation of the radio. The scan feature allows the radio to automatically search for an active channel, and priority scan enables one channel to be checked more frequently than others. This helps ensure that important communications are never missed.

The programmable channel monitor button allows you to temporarily disable channel protection, letting you monitor all signals on your channel, not just your own network. Talkaround mode enables direct communication with other radios when you're outside the range of a repeater, making sure you stay connected even in remote areas.

Safety is also a priority with the HT700 Series. A local personal attack alarm can be activated in emergencies, emitting a loud siren to deter attackers and call for assistance.
