With a full battery and in full power mode, it will give you a range of about 20 km depending on obstacles.
With the Baofeng radios, you will get 8 – 15 kilometers of transmission range under normal circumstances. In Ideal condition, you will get more than 20 kilometers of transmission range with the Baofeng radios. The range may also reduce to 5 kilometers if the condition doesn’t favor the transmission. While the range may come down or go up depending on different factors, you can boost the transmission signal using various methods.
Let us see the factors affecting the transmission range of a ham radio and how to increase the transmission range in your Baofeng ham radio.
Factors that affect the transmission range
1. Power setting
Baofeng radios come with at least 5-watt of maximum output power and some have up to 8-watt of output power. So you will get a good transmission range with your Baofeng radios if you set it to the maximum output power level. Just make sure you have enough battery left in your radio before setting it to the maximum power output level.
2. Antenna Type
You can actually increase the range by using good quality aftermarket antennas. The transmission range can be further increased by using a dual-band antenna and mounting it at a high point. If you use this technique, you can boost the transmission range up to 30 kilometers. Before purchasing an antenna, make sure that it supports connecting to the Baofeng radios.
3. Your Environment
The VHF (Very High Frequency) and UHF (Ultra High Frequency) signals from the ham radios travel in a straight line of sight. They do not bounce around along the ground, so any obstacles present in your environment may decrease the transmission range. If there are no obstacles like trees or buildings, then the transmission range will surely increase.
If you are in a tall building, then the transmission range will be increased. While it is impossible to remove all the obstacles, you can increase the transmission range by using it from a tall building.
4. Position of the repeater
Similarly, if you use a small repeater inside a building or a garage, then the signals will bet obscured to reduce the transmission range. So to get the best possible transmission range, buy a local repeater and place it on a tall tower or a building.
You can get the most transmission range from your Boafeng radios if all the above-listed factors are in your favor. You will get up to 30 kilometers of transmission range under the best of conditions. Make sure that there are minimum obstacles and you set the maximum power output level with a local repeater to get the most out of your Baofeng radios.
