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.

What is the best frequency for distance?

VHF and UHF Radios Compared - Which Is Best? 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 the range on the walkie talkie?

The maximum range for a walkie-talkie is usually around 5 miles, but some designs can go all the way to 36 miles. However, this range differs greatly depending on your surroundings, and the maximum distance listed usually refers to when the devices are transmitting between two high points.

HOW FAR CAN 2 way radios transmit?

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 UHF travel?

Since UHF transmission is limited by the visual horizon to 30–40 miles (48–64 km) and usually to shorter distances by local terrain, it allows the same frequency channels to be reused by other users in neighboring geographic areas (frequency reuse).

What band is 400 MHz?

The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use.

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.

What is the longest range 2 way radio?

1. Motorola T470 2-Way Radios. The T470 is a powerful option from Motorola; it boasts an up to a 35-mile range, and it has 22 channels and 121 privacy codes to more easily stay in touch with your party.

How far can 900 MHz travel?

The lower frequency radio waves of 900 MHz radios provide greater penetration through walls, trees and other obstacles, making it optimal for most non-line-of-sight applications. A typical AW900xTR Radio using high powered AW-15 15dbi antenna can go distances of up to 1500 feet with buildings and/or trees in the way.

How far do police radios reach?

Commercial radios like FRS/GMRS are advertised to have up to 30-40-mile range. The higher the wattage of your radio is will give you a boost in range respectively. Police radios operate in a 700/800 MHz UHF band. This gives them a considerable amount of range which is pretty good in urban areas.

What is the longest distance a walkie talkie can reach?

The range of a walkie-talkie is one of the most important factors to look for when buying this device. Regardless of solid construction, a good walkie-talkie set should provide an optimum range coverage of 25 to 30 miles on limited frequencies of 400-512 MHz with some ultra-high frequency range.

What is the best frequency for walkie-talkies?

However, UHF signals (400 – 470MHz) are better for built-up areas, giving better penetration for the same power. If you are looking for a general walkie talkie frequency, UHF is probably your best choice.

What is the difference between a walkie talkie and a 2 way radio?

A two way radio is also commonly called a transceiver, because it can both transmit and receive radio communications. In either case, the radio operates two ways; it can send and it can receive. A walkie talkie is a portable two way radio, particularly one that can be held in the hand.

Which frequency has longest range?

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz.

How far can RF signal travel?

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.

How far will a 100 watt FM transmitter reach?

If an ERP of 100 Watt is used, it is very likely that 20 kilometers of range will be reached because a 100 Watt ERP is able to propagate a strong signal as far as 20 kilometers. If an ERP of 1000 Watt is used, it is very probable that the signal will reach 20 kilometers, and it will also penetrate eventual obstacles.

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 do I extend the range of my CB radio?

The best way to extend the range of your CB, or any radio, is raise the antenna higher. Of course you will need a good quality antenna and Coax. For mobile operations the Wilson 5000 is probably the best.

Is there a walkie-talkie that can reach 100 miles?

Walkie Talkie Phones Zello PTT Button APP WiFi Mobile Radio 3G/4G Network 100 Miles Long Range Smartphone GPS Android KSUN ZL10.

How can I increase my 2 way radio range?

What two way radios have the best range?

Is VHF or UHF better for long distance?

VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication. UHF is better when using radios for indoor use like buildings or around cities.

How far can a VHF signal travel?

VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles).

Is UHF or VHF better for outdoors?

UHF is the better all around signal and is by far the most popular, so if you are in doubt, choose UHF. UHF signals don't travel quite as far outdoors as VHF signals, but they do a better job of penetrating wood, steel, and concrete, giving you better range and performance in urban environments and around buildings.
