What is VHF and UHF frequency range?
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) while VHF ranges from low band (49-108 MHz) to high band (169-216 MHz).
How many Hz is UHF?
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)….Ultra high frequency.

What is the frequency range of HF?
3 megahertz to 30 megahertz
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz.
What is the difference between VHF and HF?
VHF operates at a higher frequency range than HF, usually between 30-300 MHz. These transmissions, due to their higher frequency, penetrate through the Ionosphere, with little or no refraction. VHF propagation is ‘line of sight’ in nature and so is restricted to shorter-range communications.
What does a frequency of 400 Hz mean?
400Hz is a type of frequency within Alternating Current (AC) electrical power, which has become the standard for weapon systems, aerospace, and aircraft industries across the world. It has become the standard of the aircraft and aerospace industry because of its lightweight, reliability, and high power capability.
Is FM used on HF?
With the exception of a segment of the 10 meter band, FM phone is prohibited on the HF bands due to its large consumption of bandwidth. Each band tends to have even finer subdivisions of spectrum within which the various digital modes will congregate.
Can a technician use HF?
Technicians can talk around the world, too! Not only can Techs operate on all VHF and UHF ham radio frequencies from the 6-meter band up through the millimeter-wave bands, they also can operate on HF (high-frequency) bands, which also are known as the shortwave bands.
Is HF better than VHF?
HF communications are best suited for long distance communication between ground operators and base stations. VHF communications are best used for transmission of data between radio operators within line of sight over flat ground. VHF radio transmissions work best for line of sight communications.
What is God’s frequency Hz?
GOD’S FREQUENCY IS 39.17 MHz: THE INVESTIGATION OF PETER POPOFF.
