VHF（Very High Frequency ），甚高频， 是指频带由30 MHz 到 300 MHz的无线电电波。 UHF（Ultra High Frequency），超高频，是指频带在300-3000MHz之间的无线电电波。 这两个无线电波段广泛用于电视、调频广播、…

2023年7月17日 · UHF, short for “Ultra High Frequency,” and VHF, short for “Very High Frequency,” are two types of radio frequencies. The UHF low band goes from 378 to 512 Megahertz (MHz) and the high band from 764 to 870 MHz. On the other hand, VHF’s low band ranges from 49 to 108 MHz, and its high band from 169 to 216 MHz.

UHF and VHF are particular radio frequencies that are used by two-way radios and communication systems. A critical difference between these two frequencies is that UHF (ultra high frequency) may not travel as far as VHF (very high frequency), but it provides more bandwidth occupation.

Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). Common uses for VHF are FM radio broadcasting, television broadcasting, two way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of ...

2020年8月15日 · What are the differences between UHF and VHF? In general, VHF radios operate in the 138-174 MHz frequency band and UHF radios operate in the 400-512 MHz frequency band making UHF roughly three times higher in frequency than VHF.

VHF、UHF的频率范围 1、VHF意思是甚高频， 2、UHF意思是超高频，即ultra-high freqency ，电视搜台显示的是当前频率段名，最高不超过470M，因为带增补的高频头标准就是470M

VHF又称为米波频段，是Very High Frequency的缩写，频带范围为30～300MHz，无线电波波长为10～1m。 UHF 则称为分米波频段，是Ultra High Frequency的缩写，频带范围为300～3000MHz，无线电波长为1m～1dm。

2025年1月27日 · When it comes to radio communication, UHF (Ultra High Frequency) and VHF (Very High Frequency) are the two most commonly used frequency bands. But how do they differ, and which one is right for your needs? Understanding the basics of UHF and VHF can help you choose the best option for your specific application. 1. What Are UHF and VHF?

UHF (Ultra High Frequency) and VHF (Very High Frequency) are two different frequency bands used for various communication purposes. UHF operates in the frequency range of 300 MHz to 3 GHz, while VHF operates in the range of 30 MHz to 300 MHz. One key difference between UHF and VHF is their wavelength.
