The Icom AT-140 Marine Auto Antenna Tuner TEE AT140 is a must-have accessory for any serious marine radio enthusiast. This state-of-the-art tuner is designed to automatically match your marine VHF radio with any antenna, ensuring optimal performance and clarity of communication.

The AT-140 is also equipped with a built-in relay that automatically switches the antenna between transmit and receive modes, ensuring that your radio and antenna are never inadvertently connected in the wrong configuration. This feature helps to protect your radio and antenna from damage and ensures that you always have a clear and reliable communication link.
The tuner is built to withstand the harsh marine environment, with a rugged and waterproof enclosure that is resistant to salt spray and corrosion. The AT-140 is also easy to install, with clear instructions and easy-to-use mounting hardware included in the box.
