Some thoughts about increasing survival radio range...
Increasing Range With Your Antenna
First off, an antenna can be a factor that can increase or decrease your range. By swapping out antennas you can change the characteristics of the radio and increase your range. Think about it like this. An antenna radiates signals produced by your radio.
And by increasing the height of your antenna, you can improve the distance your signal radiates. Now there is one myth about antennas. Sometimes you'll see a wattage rating attached to an antenna. And some people think that this is some kind of power rating. But that's not the power of the antenna.
An antenna doesn't have its own strength. All it does is radiate. So here’s what you want to do. Get your antenna as high up as possible. That's the simplest way you'll increase its effectiveness, unless you want to take things a step further.
Another Idea: Repeaters
Now here's another idea that most people don't think about. Repeaters. What is a repeater? Very simply, its a device that receives and retransmits a signal. They are used to increase radio ranges. So if you need range beyond line of sight, then repeaters become important. Ham radios use repeaters.
So where are these repeaters? They are located in high spots like tops of mountains, buildings or towers. That’s what gives them such long ranges. Now what’s interesting is GMRS radios can use repeaters too.
Matter of fact, some GMRS radios have repeater capabilities. Two examples are the Motorola MR355R or the Garmin Rhino 130 which has 8 repeater frequencies.
