How far can a handheld UHF radio transmit?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)
| Average Range Guidelines * | ||
|---|---|---|
| Wattage | Flat Open Terrain (miles) | Suburban Locations (miles) |
| 4 watts (UHF) | 4 – 6 | 2½ – 4½ |
| 5 watts (VHF) | 4½ – 6 | 2 – 4 |
| 12 watt CB SSB (HF) | 8 – 15 | 5 – 8 |
How far will a 25 watt UHF radio transmit?
60 nautical miles
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.
Which radio frequency is best for long distance?
VHF (136 – 174MHz) signals generally work best outdoors, giving a somewhat longer range for the same power output than UHF (400 – 470MHz).
How far is 400 470 MHz range?
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.
How do I choose a UHF radio?
A lower gain UHF radio antenna is best for distance over flat terrain where a higher gain antenna will suit best. Even with lower gain, it won’t guarantee 100% clear signal beyond obstacles such as hills and buildings. You can often buy a CB UHF antenna in a kit or pack along with your UHF radio.
What is the range of UHF radio?
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter).
What travels farther VHF or UHF?
VHF radio signals are on the low end of the frequency scale when compared to UHF. Although, VHF signal wavelength is longer, allowing it to travel farther than UHF.
How can I boost my handheld radio signal?
Three Tips for Extending Two Way Radio Range
- Improve the antenna – Larger antennas can boost the range of a two way radio.
- Use a repeater – Signal repeaters can help extend range.
- Make sure your batteries are good – Low battery strength can impact the strength of your radio signal.
