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

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 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'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
How can you tell the difference between a CB antenna and a VHF antenna?
The CB antenna is made for a limited band of frequencies and the VHF is a wide band antenna made for higher freqs. A CB antenna will not make a good tv antenna. A CB ant. is mounted on the vertical and tv ants. are mounted horiz. in the USA. VHF antennas are much smaller as they are for higher frequencies. Usually, they have many elements (rods) and will go from long in the back to short in the front. Certain CB antennas (beams) are mounted horizontally, but all of the elements are roughly the same length - and about twice as long as a VHF antenna. The elements on a horizontal CB antenna are roughly 18 feet from end to end.
Why is the height of the VHF antennae important?
Because VHF signals have a line of sight limitation.
