Performance Features

Uniden Atlantis 270 Handheld Floating 2-Way 1/2,5/6 Watt VHF Marine Radio, JIS7/IPX7 Submersible Waterproof level and Designed to Float, All USA, International, and Canadian Marine Channels, - Black Color

This VHF radio provides two-way communication when you are on the water. You can communicate when at sea with the people on land and the sea with you. With NOAA (National Oceanic and Atmospheric Administration) emergency weather channels, you are always in the know when the weather changes. 

It has all USA and Canadian channels from 1-88. They allow using it in the area of your choice from the sea to the shore. With a 6W power output, it can give you a strong signal over a wide area. Its mile range is rated at 5-7 miles. 

You can select the output power from 1, 2.5, or 6watts. It also has a BOOST (PTT) key so that you can enable 6W power for a short time. Using more watts does deplete the batter faster.

With the Uniden Atlantis 270, you can adapt to different environments. Say you want to communicate to kayakers that are only three miles away, a lower output is all you need, and thankfully, you will still sound as clear as day. 

However, atmospheric obscurants like being around the hilly countryside will affect the signal range as with all VHF radios. As such, the Uniden Atlantis 270 is more useful when you do not have any obstructions. 

The squelch feature that filters background noise. While this is useful when the ocean is acting up with raging waves, you may also miss out on the weak signals that may be important. 

Water Resistance

The Uniden Atlantis 270 is rated at JIS7/IPX7. It can withstand drops in 1-meter water depth for 30 minutes. If it gets into contact with salt water, just rinse it with fresh water and leave it to dry; no damage done.

Sound distortions in the device are caused by water. You can rectify this by shaking the radio to remove excess water for smoother sound should it get wet or if its dropped overboard.

To ensure that your radio is always waterproof under the specified depth and time, you will want to ensure the rubber seals fit correctly and are in good condition. Note that the charger is not waterproof.

Atlantis 270 Battery Life

Long boating sessions of over 10 hours require a marine radio that can withstand use without draining the battery. We found that even though Uniden has indicated that this device has a 10-hour battery life, it can only manage half the time with light use. So if most of your boating trips are longer full day trips and you have no way of charging on your boat this might not be the best radio for you.

It is powered by one rechargeable Lithium-Ion battery. You get AC and DC adapters to recharge your radio; so, on most boats you can keep it charged if needed. You can use your boat’s 12volt system or charge it or back at the house with the AC adapter. A charging cradle is also included.

Warranty

The Uniden Atlantis 270 has a 3-year warranty. It is covered for defects in craftsmanship and materials as a result of the manufacturer; Uniden. As such, the warranty will be void if you alter the design using a conversion kit or failing to take the proper measures to maintain the device.

Like the Atlantis 270, this radio has a bright LCD screen that can be used day and night. 

The major distinction between the two devices is that the total output of MHS75 is 5W. It has a shorter transmission range than the Atlantis 270, so you are a bit limited to how far out you want to communicate. It also has selectable 1 and 2.5 output powers and a BOOST key.
