Frequently Asked Questions (FAQs)

1. What is the difference between VHF and UHF radios?
VHF radios are used primarily for ship-to-ship and ship-to-shore communication over water. UHF radios have shorter range but better signal penetration for onboard communication.

2. Are VHF radios mandatory on ships?
Yes, VHF radios are required for SOLAS-compliant ships and are part of the Global Maritime Distress and Safety System (GMDSS).

3. Which VHF radios are GMDSS compliant?
Models like ICOM IC-GM1600E, Jotron TR20, and Entel HT649 are IMO-certified GMDSS portable radios with waterproof and float-free designs.

4. Can UHF radios be used outside the vessel?
UHF radios are primarily for onboard use. For external communication, VHF is the preferred marine band due to its longer range over water.

5. What accessories are supplied with portable radios?
Typical accessories include lithium battery packs, chargers, belt clips, antennas, and waterproof carry cases.

6. Are the radios waterproof?
Yes, marine VHF and UHF radios are generally IP67 or IP68 rated, making them waterproof and floatable.

7. Do I need a license for VHF/UHF radio use?
Yes, many countries require radio licensing. We assist clients in licensing and programming of marine radio channels as per authority guidelines.

8. What is the battery backup time?
GMDSS radios provide 8 hours on lithium battery in distress mode. Standard models may run 12–20 hours depending on usage and model.

9. Can I use marine radios for crew communication?
Yes. Many ships use UHF radios for internal crew operations such as cargo handling, engine room communication, and security.
