How To Find a Good Two-Way Radio Frequency

How to find two-way radio frequency

Before going to the mechanical parts, we need to understand some basics about two-way radio. Generally, two-way radio is a radio system where users can access communication from both sides. Besides, it consists of a transmitter and receiver. It is also known as a transceiver. So, the process is to receive frequency from one end and feedback it by the transmission process. For example- Waitaki and modern-day mobile as well.

Do you want to know about two-way radio frequency? How to find the rate? We are not going to disappoint you, so let’s start.

Things you should know about two-way radio frequency communications

If you’re using a two-way frequency to communicate with someone then you should learn about some principles. These help you to communicate more effectively. However, the rules are:

  • For communicating in a long-distance, the frequency should be lower.
  • However, for better penetration, you need a higher frequency.

If you follow these rules, the quality of your communication should be better.

Ways to find two-way radio frequency

Two-way, it seems simple right? But in terms of frequency, it is a bit different. Firstly, if you want to receive any radio frequency, you need to move on a high platform. The higher the device, the greater the rate it receives and transmit. In terms of two-way radio frequency, the process is similar. The difference is that one method works as a receiver and transmitter at the same time.

As we know, the earth is curvier in shape, but radiofrequency work straight. So, the possibility of interference is exceptionally high due to the interception of earth shape—also, the lower atmosphere mixed with numerous waves and frequency that intervene in the radio frequency. Importantly, tow-way radio vibration works parallel and straight, so avoid the lower ground.

According to the position of the users, the frequency varies. Frequency increase with the higher location of the device. Generally, the rate reaches 4-5 miles in the earth’s atmosphere. But you can expand the range by raising the antenna height.  For example,- If you increase the antenna height of your radio by 6 feet or 1.82 meters, the frequency distance will be calculated by the horizon(km)= 3.569 x √height (meters). The equation is to measure the range of the frequency. According to formula, the background is 4.83km or 2.99 miles away.

In a ham radio system, there are tow receivers and transmitters. So, if one is significantly higher positions such as radio station tower and other is at ground level, the range will be high. But at the same time, each location is at ground level, and then the field will below. Mostly it depends on the position and height of your device antenna.

Problems to find two-way radio frequency

Few restrictions are finding tow-way radio frequency such as obstacles, low power supply, and flat transmission rate. Moreover, radiofrequency moves in a straight line, but obstructions may reduce the wavelength by blocking. Besides, low battery capacity and the transmitter will not be able to send frequency to farther distance. These are the fundamental problem to find two-way radiofrequency.

Find a Good Two-Way Radio Frequency

Types of two-way radio frequency

There are two different types of radiofrequency according to their wavelength. They are known as VHF (Very High Frequency) and UHF (Ultra High Frequency). Based on features and use, they are distinctively different

VHF (Very High Frequency):

The wavelength of this frequency is more significant. So, it can transmit frequency in a more extended range. In the two-way radio system, VHF is accessible for long-range communication, and larger wavelength can reach a farther distance. For instance- VHF use in outdoor applications. Besides, it consumes less power. However, due to longer wavelengths, it is easily obstructed, and frequency strength reduces.

UHF (Ultra High Frequency):

The difference is in wavelength. UHF consists of a much shorter wavelength, and its range is lower than VHF. But due to shorter wavelengths in the two-way radio system, it works as an indoor close-range communication service. For example- In an industrial environment, workers need to be communicated through interference, so UHF is the best option.

It allows connecting with several devices at the same time. If you want to find out UHF two-way radio frequency, then use the tool to the full extent. Due to short-wavelength, it can easily penetrate the obstacles and maintain a high-frequency level.

Types of Communication

With two-way communication devices, you can talk with a single person as well as a group of people. The devices have been a great tool for many. Besides, it also allows you to talk privately.

It’s an excellent feature of a two-way radio that you can communicate with your partner instantly. However, for that, you need to press the PPT button. And after that send any messages you want.

Moreover, you can connect the radio to multiple devices too. Therefore you won’t have to repeat the message to everyone on the team.


Q. What is the best frequency for two-way radios?

A. The best frequency to communicate in two-way radios is between 400 to 550 MHz. However, UHF is a great option with this range, specially if there are any barriers between the radios.

Q. Is VHF or UHF better?

A. The answer depends on how and where you’re going to use them. UHF is better for indoor use. They’re pretty efficient in penetrating buildings. However, they also can operate at higher frequencies. On the other hand, VHF is excellent for long-distance communication. Besides, good for both indoor and outdoor use.

Q. What frequency is two-way radio?

A two radio has variable frequency options. You can choose from 150 MHz to 900 Mhz. However, depending on the situation, you need to tune in to the best frequency range. Unlike some other communication devices, two-way radio frequency travels in a straight line.

Two-way communication is an excellent method to contact your partner. Hope our guide to find good two-way radio frequency will help you. However, without having a good frequency, it’s tough to have effective communication. Hence, this guide should be useful for people who use two-way radios for communications.
