UHF vs VHF Wireless Microphones: Which One Should You Choose?
The main difference between UHF and VHF wireless microphones is the frequency range they operate on. UHF stands for Ultra High Frequency, and VHF stands for Very High Frequency.
UHF microphones operate at higher frequencies (450 MHz to 952 MHz), while VHF microphones operate at lower frequencies (49 MHz to 216 MHz).
This difference in frequency range has a number of implications for the performance of UHF and VHF wireless microphones :
Sound quality: UHF microphones generally have better sound quality than VHF microphones. This is because UHF signals are less susceptible to interference from other electronic devices.
Range: UHF microphones also tend to have a longer range than VHF microphones. This is because UHF signals are less affected by obstacles such as walls and furniture.
Interference: UHF microphones are less susceptible to interference from other electronic devices than VHF microphones. This is because the UHF frequency range is less crowded than the VHF frequency range.
Cost: UHF microphones are generally more expensive than VHF microphones. This is because UHF technology is more complex.
Which one is better?
The best type of wireless microphone for you will depend on your specific needs. If you need a microphone with the best possible sound quality and range, and you are willing to pay more, then a UHF microphone is the best choice. If you are on a budget, or if you do not need the best possible sound quality and range, then a VHF microphone may be a good option for you.
Here is a table that summarises the key differences between UHF and VHF wireless microphones:

Which one should I choose?
If you are using your wireless microphone in a noisy environment, or if you need a microphone with the best possible sound quality and range, then a UHF microphone is the best choice. UHF microphones are also a good choice if you are using multiple wireless microphones simultaneously, as they are less susceptible to interference.
Here are a few recommended VHF & UHF Wireless Mike:
Single Channel UHF Frequency Mikes:
AHUJA 400 UH Portable Wireless Mike
STUDIOMASTER XR 20H Wireless Mike
Single Channel VHF Frequency Mike:
Dual Channel UHF Frequency Mikes:
STUDIOMASTER XR 40 HH Wireless Mike
STUDIOMASTER XR 40 LL Wireless Mike
Dual Channel VHF Frequency Mikes:
If you are on a budget, or if you are using your wireless microphone in a quiet environment and do not need the best possible sound quality and range, then a VHF microphone may be a good option for you.
Ultimately, the best way to decide which type of wireless microphone is right for you is to consider your specific needs and budget.
good explanation. I was wondering which mike frequency will be better. I am buying ahuja 700u2 for my church.
