history of vhf radio
Why is the height a vhf radio antenna important?
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.
Can a uhf vhf antenna receive FM radio broadcast?
Any antenna can receive anything, but not very well unless it's the correct length for the frequency you're trying to receive. Yes, this antenna will work well so you will not need a special FM only antenna.
What is the maximum range for a VHF radio?
VHF is in the range 30 to 300 MHz.

Why is the Height of VHF radio important?
Because VHF signals have a line of sight limitation.
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.
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.
What is communication system of the aircraft?
Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.
Why is the height of the VHF antennae important?
Because VHF signals have a line of sight limitation.
Where may a person purchase a Motorola brand VHF antenna online?
There are many places online to buy a VHF antenna. The best place would be the Motorola website. They also sell them at Amazon, Alie Express, and Radio Communications online.
Can you coil a vhf antenna?
no

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.
What is gain of typical TV FM vhf only home antenna?
The actual numbers are not as important as the knowledge that generally speaking, the larger the antenna the more gain it will have. Three other main factors are the Distance from the transmitting antennas are from your location and the Height of your antenna above the ground and what Obstructions there might be between the two antennas.
