UNIDEN ATLANTIS 250 VHF MARINE RADIO 5W how many miles distance over sea can it transmit thanks?

Answer 1

most handheld marine radios get between 5 to 14 miles range boat to land
as for over the sea you probably get about 4 miles boat to boat

Answer 2

5 miles?
It really depend one many factors. Weather conditions, how high the antenna is and the gain of the antenna. Even the type of antenna. You ever hear of a Yagi antenna? You may have not, but, I bet you have seen them. On the roofs of houses they were very common before cable TV. A Yagi is a directional antenna, that why we see people turning them to get better reception. Most antennas we see on boats are just a straight looking wire to us. But, it is tuned to the wavelength of the Transmitter/Receiver. If we know the Formula we can make a ¼, ½, or full wavelength antenna out of a Coat Hanger. The Yagi has a higher gain and can transmit further, yet, better in the direction it pointed. Sun spot activity can actually determine distance. VHF is the same VHF TV operate on, but, higher on the frequency band, so, interference is another factor. So, with this said;
IF, you in the ocean and it is water, water everywhere .......... you "can" transmit as far as the eye can see. "IF" the conditions are right.

Answer 3

Uniden Atlantis 250

Answer 4

VHF radios are basically "line of sight" radios. Since the horizon is approx. 12 miles away that is what you can expect on a clear day with no obstructions. If you move higher up on the boat you may get a bit more distance.

Answer 5

It depend's on how high up the antenna is, VHF Marine radio's work on "Line Of Sight" (one antenna has to see the other one) the curvature of the Earth gets in the way over a distance of 20 miles (depending on antenna hight), I have an 8' ant. my friend has his mounted on his sail boat mast up high, he gets much greater distance than I do.

Answer 6

I use GME Electrophone mostly. I also have Icom and my sailing clubs use uniden as well. They are all equally good - invest in the waterproof pouches, we regularly get 6 or 7 hours straight. We recharge after every use, and maintain charge at least every six weeks in the off season. The batteries are original and at least four years old with this treatment.. I have not used the other two.

Answer 7

LESS THAN 7 MILES. 5WATTS IS NOT A VERY POWERFUL RADIO. YOU NEED ABOUT 20 WATTS OR MORE TO GET DISTANCE. A GOOD ANTENNA HELPS RECEIVE FROM LONG DISTANCE BUT TO TRANSMIT YOU NEED TO STEP UP THE WATTAGE.
