The 5 watt radio can reach up to 12 miles or more. Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.
How far will a 4 watt CB transmit?
Transmitter power is limited to 4 watts in the US and the EU. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.
How far away do radios work?
Many consumer radios advertise a 30-mile range, but the truth is that most basic consumer radios will not provide anything near this distance. On average, a standard two-way radio is capable of communicating around half of a mile to 2 miles.
How far can a 10w radio transmit?
Thus the typical ranges with around 400 MHz frequency range with 1 W transmitter power are up to ~30 kilometers and up to ~80 kilometers with 10 W transmitter power. See sample picture of a RF link functional factors at the end of this document. The links can be extended by using repeater radio stations.
Which is better GMRS or MURS?
GMRS handheld radios have typically two to five watts transmitter power. … GMRS operation requires an FCC license. At MURS frequencies, signals bend over hills better, but GMRS signals are better at bouncing off of surfaces and penetrating into/escaping out of buildings.
How far will 25 watts transmit?
For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.
How do I increase the range on my CB radio?
How to Increase the Receiving Range on a CB Radio
- Install an antenna specifically manufactured for use with CB radios. …
- Place your antenna as high as possible, in a place where radio signals can hit it from 360 degrees. …
- Adjust the squelch on your radio so that it blocks out static, but is not maxed out.
How far will a 100 watt FM transmitter reach?
If 100 Watt ERP is used, it’s very likely that 20 kilometer of range will be reached because 100 Watt ERP is able to propagate a strong signal 20 kilometer. If 1000 Watts of ERP power is used, it is very provably the signal will reach 20 kilometer, but moreover it will helps to penetrate eventual obstacles.
Is VHF or UHF better?
In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. … VHF radio signals tend to degrade more than UHF signals indoors.
How far can a 2 watt radio transmit?
So, a 2-watt walkie-talkie might broadcast within a range of 1.5 miles; 3 watts = 2 miles; 4 watts = 2.5 miles; 5 watts = 3 miles; and so on. Actual distances may vary widely based on weather, UHF vs. VHF, etc. But these are good, general rules of thumb to go by when shopping for a new radio system.
