Advantages of UHF Radios: How it Differ from VHF

UHF is the abbreviation of Ultra-High Frequency. This radio can pick up signals with short waves, such as the 430MHz frequency equates to a 70-cm radio wave. These waves are smaller compared to the other frequency waves. For example, the 144MHz frequency has a 2-meter radio wave. The spectrum of UHF radio can go up to 1 GHz.

UHF radios like Oricom UHF are widely used in several industries such as cell phones, television broadcasting, Wi-Fi and Bluetooth, cordless phones, satellite phones, GPS, personal radio services, and several other applications.

Now that you understand what a UHF radio is let’s look at these devices’ benefits.

The benefits of UHF devices are:

Portability

One of the best things about having UHF radios is their portability. You can also boost the signal with an external antenna. You can keep the radio in your pocket or bag and pass on information whenever possible. And as the range of these devices is around 40 to 60 km, you don’t have to worry about the signal strength.

Can place it in your dashboard & No issue with the solar activity

As the size of the radio is compact, you can place it on your dashboard easily. And, being resistant to solar activity (UV rays, flares, heat), you can leave it on the dashboard on sunny days as well.

Long range

The range is also a strong reason these radios became so popular. It is built around a single loop of the antenna from several cm to several feet across. You can use the bouncing signals off the ionosphere to communicate with someone as far as 100 km.

Less electronic noise

The electronic noise is less in the lower end of the UHF band like in Oricom UHF. So, for example, the lower the bands are, the less interference with the power lines, microwave ovens, or machines using microwaves.

Best for hill/mountain regions

When the radio signal is of short wavelength, the radios perform well in hilly or mountainous areas. It is the same with TV transmission in mountain regions.

Now, let’s look at the difference between UHF and VHF radios:

  • Two-way radios are great for many businesses, but you need to know what your employees need to form these radios. When this situation comes, the biggest question that arises in the management is about the choice between UHF and VHF radios.
  • UHF is a necessary device for public safety officials and workers. These devices are used for coon purposes like television, phones, and ham radio operators. Warehouses, security officials, casinos, manufacturing, mining, construction, health care and many more sectors use the UHF radio.
  • VHF is used in communication on ships/boats and marine personnel. It is a necessary device for people who sail for months. 
  • It helps connect to the nearby boaters if any emergencies arise. 
  • The main difference between UHF and VHF is the broadcasting level.

UHF can broadcast between 300MHz and 3GHz. VHF can broadcast between 30MHz and 300MHz. 

In the earlier years, UHF and VHF were widely used in various sectors. But today, VHF has replaced UHF in the public safety field as tech improved. However, different police departments and fire departments still use UHF radios for work.

Now, the next time you decide to buy a two-way radio, which type would you choose? If you have understood anything from this article, it will benefit you in future purchases.
