Q:What is the range on this unit? How far offshore will I be able to communicate?Asked on 9/13/2009 by David from Beaumont, Texas
A:When looking at VHF radios the rule of thumb is 1 watt equals 1 mile. It also depends on your surroundings. Rather you are in a wooded area or in a cove surrounded by cliffs. With that being said on a clear day out on the water you are looking at about 25 miles.Answered on 9/16/2009 by Chad @ Overton's from Greenville, NC
A:The 1 watt per mile rule is no where near true. Working for an antenna tower manufacturer and a little reasearch on the shakespere website shows a lot of variables that effect range. Especially terrain. You will have better range on an open lake, or out at sea, than you will on a river.
Here is the formula. You factor the square root of the height to the tip of your antenna above the water line measured in feet. Multiply that by 1.42 that gives you a range. Now you must know the hieght of the antenna that you are trying to contact and perform the same formula. Add both numbers together, that is your range.
Two boats trying to reach each other with an 8 foot antenna, would be able to do so at a maximum range of about 10 miles.
The higher your antenna is, the farther the range you have.Answered on 10/2/2009 by ChadW - USCG Aux from IL
