v. t. e. Very high frequency ( VHF) is the ITU designation [1] 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. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high ...
Mar 12, 2019 · UHF stands for “Ultra High Frequency” while VHF stands for “Very High Frequency.” UHF can range from low band (378-512 MHz) to high band (764-870 MHz). UHF has shorter frequency waves and can penetrate close distance obstacles. Therefore, it is great for indoor applications.

IV. V. VI. v. t. e. Ultra high frequency ( UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter ). Radio waves with frequencies above the UHF band fall into the super-high ...

From the table, we see that VHF is in the range 30-300 MHz (30 Million-300 Million cycles per second). At the very least then, if someone says they need a "VHF antenna", you should now understand that the antenna should transmit or receive electromagnetic waves that have a frequency of 30-300 MHz. Table 1. Chart of Common Frequency Bands.
