How to choose a wireless microphone, and explanation on the differences between VHF and UHF in electronic component platforms.

More and more people are paying attention to microphone selection, especially as wireless microphones are versatile and convenient for various scenarios. When selecting a wireless microphone, you often come across two types: VHF and UHF, which can be confusing for many beginners. Next, I will share the differences between them on Unikey to help you make a choice.

VHF and UHF are connection methods

When we search for wireless microphones on platforms like electronic component platforms, we often see labels such as VHF and UHF. These refer to the signal transmission methods of wireless microphones. VHF and UHF stand for Very High Frequency and Ultra High Frequency, also known as the V-band and U-band. VHF refers to radio waves between thirty and three hundred megahertz, while UHF refers to radio waves between three hundred and three thousand megahertz.

VHF and UHF signal transmissions are different

After understanding the meanings of VHF and UHF, it is important to note that their signal transmissions are different. In the case of VHF, wireless microphones use several stages of frequency multiplication circuits on the transmitter to obtain a high signal. The signal wave frequency on the transmitter is a fixed value. On the other hand, most VHF transmitters utilize phase-locked loop technology, allowing the high-frequency signals they transmit to be adjusted as needed. Likewise, VHF receivers can also be adjustable when receiving signals.

VHF and UHF have different anti-interference capabilities

When selecting a wireless microphone, it's important to understand that VHF and UHF have different anti-interference capabilities, especially when frequently used outdoors where signal interference factors need to be considered. VHF operates at lower frequencies, typically ranging from 180MHz to 280MHz. In environments with six or more surrounding bands, VHF microphones may experience interference. On the other hand, UHF operates at higher frequencies, typically between 500MHz and 900MHz, providing stronger anti-interference capabilities. It requires the presence of sixty or more surrounding bands for interference to occur.

The above information highlights the differences between VHF and UHF when purchasing a wireless microphone. Understanding these differences allows us to make informed choices. By leveraging Unikey, we can source products, compare prices, and find wireless microphones that meet our requirements in terms of user experience and pricing.
