What is difference between UHF and VHF antenna?
What is difference between UHF and VHF antenna?
The wavelengths of UHF (ultra-high frequency) are short so antennas for UHF two-way radios are typically small and stubby in size. VHF requires a slightly larger antenna to improve its range and how far it will travel. VHF antennas can receive channels 2 through 13 while UHF antennas can receive channels 14 through 83.
Can you use a VHF antenna for UHF?
If you live in an area where both UHF and VHF frequency bands are transmitted, you can often use just one antenna, like one of our ClearStream MAX antennas. Generally, our bowtie antennas can receive high-VHF broadcasts.
What is VHF and UHF antennas?
VHF antennas and UHF antennas use very high frequency (VHF) and ultra-high frequency (UHF) signals for two-way radio, public safety, and commercial communications. VHF is the range of radio frequency (RF) signals from 30 to 300 MHz. UHF is the range between 300 MHz and 3 GHz.
Which one is better UHF or VHF?
VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
What is VHF antenna?
VHF is the first band at which wavelengths are small enough that efficient transmitting antennas are short enough to mount on vehicles and handheld devices, a quarter wave whip antenna at VHF frequencies is 25 cm to 2.5 meter (10 inches to 8 feet) long.
How does a VHF antenna work?
The main purpose of a VHF antenna is to provide a radiator for the power that the transmitter in the radio produces and to radiate this energy in the correct direction.

What makes a rabbit ear antenna a UHF antenna?
Many rabbit ear sets include a loop in addition to the old familiar V, making it a UHF and VHF antenna antenna. Most modern indoor antennas, such as the flat panel from 1byone below, have looped dipoles inside the plastic casing for getting the UHF band.
How big is the dipole on a UHF antenna?
Signals toward the upper end of UHF aren’t much longer than one foot. The antenna that most efficiently picks up a given wavelength will have a dipole whose length is some fixed proportion to the length of the wave. For example, half the length of the wave.
