VHF signals are essentially Line of sight transmissions (LOS). Like all radio waves they are attenuated by objects in their path. Raising the aerial above the level of the interferring objects while still maintaining an integral waveform (Usually using an artificial ground plane or aerials less than 1/2 lambna), reduces the attenuation and prevents distortion of the polarization pattern thus leading to an efficient transmission path.

EQ-20 why is the height of a VHF radio antenna important?
VHF radios work by the line of sight principle
Why is the height of a vhf radio antenna i?
The height of a VHF radio antenna is crucial because it affects the radio signal's range and quality. A taller antenna can enhance line-of-sight communication, reducing obstacles and interference, which is particularly important for VHF signals that travel via direct wave propagation. Additionally, the height can impact the antenna's impedance and radiation pattern, optimizing performance for specific applications.

Can you coil a vhf antenna?
no
Why is the height of a VHF radio antenna important on boats?
VHF is "line of sight" communication only, as the signal travels in a straight line (like visible light). A taller antenna will be able to "see further" over the horizon and thus have longer range.
How do you receive vhf?
You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.
Can a uhf antenna pick up vhf signals as well?
Yes, a UHF antenna can pick up VHF signals, but not well. The size difference makes the uhf antenna "inefficient" for the longer vhf wave length, but some energy can be received by the uhf antenna.
Why is height vhf radio antenna on a boat important?
The height of a VHF radio antenna on a boat is crucial for maximizing communication range and effectiveness. A higher antenna allows for a clearer line of sight, reducing obstructions from the boat's structure or surrounding obstacles, which can otherwise limit signal transmission and reception. Additionally, a taller antenna can enhance the ability to communicate over longer distances, especially in open water where other vessels or land might be far away. Overall, proper antenna height is essential for safety and effective communication while at sea.
Why would a household still need a VHF antenna?
A household would still need a VHF antenna if their broadcaster is using a tower that broadcasts signals using VHF. You can check this by calling your cable service provider.
What is vhf antenna?
A VHF antenna is a type of antenna designed to operate in the Very High Frequency (VHF) range of the electromagnetic spectrum, typically from 30 MHz to 300 MHz. These antennas are commonly used for various applications, including television broadcasting, FM radio, and two-way communication systems. VHF antennas come in various designs, such as dipole, monopole, and vertical, each suited for specific reception and transmission needs. Their effective range and performance depend on factors like design, height, and surrounding environment.
What's a good antenna for a TV?
Getting a VHF antenna will allow the TV to have a strong signals and get the programs that you would need. Also, UHF could be another alternative to VHF.
Should you use UHF antenna with digital converter box or VHF?
You need a VHF/UHF antenna (channels 2 to 60 ). Check out: http://www.fcc.gov/cgb/consumerfacts/digitaltv.html
