At SEANAV, we specialize in the installation, repair, and supply of HF radio systems for marine use across India.

Our team provides complete services—from system integration to troubleshooting. We offer a variety of IMO-compliant HF radios, including transceivers, tuners, and antennas. Whether you need a new setup or want to repair an existing one, SEANAV has the right solution for your vessel.
