Very high frequency (VHF) is the ITU designation [1] [2] [3] for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.

2023年7月17日 · In this article, we’ll explain what UHF and VHF radios are, how they work, and give tips on which one is right for you. What are UHF and VHF? UHF, short for “Ultra High Frequency,” and VHF, short for “Very High Frequency,” are two types of radio frequencies.

The first thing to know about UHF vs VHF is that UHF radio waves are shorter than VHF – 12 to 24 inches – so they don’t need big antennas, making them less conspicuous. Radio range is also shortened, but you get greater bandwidth occupation.

2020年6月29日 · VHF refers to radio waves operating in the range of 30 to 300 megahertz with a shorter wavelength than high-frequency (HF) bands. These bands, as with those in the UHF spectrum, are limited to a range within the line of sight (LOS), since they are not refracted by the ionosphere like lower frequency bands.

2025年2月16日 · VHF, conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz. VHF signals are widely employed for television and radio transmissions.

2020年8月15日 · Explore the advantages of using UHF vs VHF radio frequencies along with the situations where you should choose VHF vs UHF. Our experts breakdown real world applications for each frequency band along with addressing technical differences.

The principle of VHF (Very High Frequency) refers to the use of radio waves with frequencies between 30 and 300 megahertz. This article provides an overview of how VHF works and its applications in various industries, including broadcasting, aviation, and maritime communication.

HF, VHF, and UHF stand for High Frequency, Very High Frequency, and Ultra High Frequency, respectively. But before you understand what that means and how they all differ, it's important to know more about the system that organises all these terms.

Very high frequency (VHF) is an ITU label of radio frequencies. [1] The designation has all frequencies between 30 megahertz to 300 megahertz. Behind the VHF frequencies is called high frequency (HF).
