There are many things to consider when shopping for an antenna. If you’re considering installing an antenna, you might be wondering what characteristics to look for based on the type of station you listen to or download. You might also be wondering if there are any benefits to newer antennas that were not available when your grandparents listened to the radio. Here’s what you need to know about the different types of antennas and how they work.
A brief look at radio antenna
Radio antennas have dramatically changed the way we see the world and each other. From the beginning of radio broadcasting, they have provided us with a powerful tool for empathy. They have also led to conflict and murder. A group would use radio waves to spread hatred and fear among others, while another would use them to broadcast love and hope.
The story of radio antennas begins over 100 years ago when Alexander Graham Bell discovered that using a simple metal dish could make wireless communication possible. Since then, many different companies and individuals have tried to profit from this technology, often destroying the innocent lives of those nearby while trying to expand their own.
Type of radio frequencies
Two types of sound- waves attract a person’s attention, low-frequency (and centered around 1kHz) and high-frequency (and centered around 20kHz). The higher the frequency, the more easily it affects the brain; the lower the frequency, the more difficult it is for our ears to hear.
On the other hand, the radio frequencies run much higher than the ones you can hear. AM operates at 525–1606.5 Kilo Hertz kHz, while the FM 88 to 108 MegaHertz MHz (where hertz is the unit defined as one cycle per second).
Amplitude Modulation – AM Radio
Amplitude Modulation (AM) is a form of digital signal processing originally developed by Professors Barry Seth and Stanley Prusak. AM radio and television broadcasting and many digital audio applications such as MP3 music downloads and podcasts use Amplitude Modulation.
The application of this technology is novel, as it allows for transmission of two subcarriers simultaneously over a broad frequency range, thus enabling multiple input channels at higher rates than are possible using conventional transmitters/receivers. A low-pass filter connects the two subcarriers which ramp up the signal to a certain frequency called the carrier frequency.
Frequency Modulation – FM Radio
The US military and intelligence communities use Frequency Modulation as a method of communication. The basic concept is to create stepped and repeated bursts of radio energy, modulated at specific frequencies. These bursts are used to convey information like voice, radar, and television signals.
Frequency Modulation was originally used for radar and television communication but it has since become a commonly used form of wireless communication within mobile phones, systems inside computers, and even in meteorology.
First, it is important to understand what kind of antenna you plan to purchase. This will help you determine if there is a better price or better quality product available. Antennas come in different wattages and have different designs which can affect the strength of your signal.
Second, it is important to understand the indoor vs outdoor propagation characteristics of the equipment you plan to purchase.
Finally, you should know if there are any hidden costs associated with purchasing the item such as shipping or installation.
Indoor FM Radio Antenna
There are several benefits to using an indoor FM antenna.
The first and most obvious is that it lets you listen to music without interference from other stations listening nearby. FM radio waves carry much longer distances than AM radio waves, so using an indoor FM Radio Antenna allows you to receive signals from areas that are farther away than those closer to your location.
You can use an indoor FM antenna to get better reception both indoors and out. Attending a concert or a sporting event can be more enjoyable when there is an increased amount of FM broadcasting over local airwaves.
Outdoor FM Radio Antenna
Outdoor FM antennas were made for a variety of outdoor environments. That means they’ll reliably deliver your signals to those who are receptive. Specifically, FM antennas are designed to use in thick woods or other challenging conditions that would impede your signal.
FM antennas can handle strong winds and rain, too, making them a reliable option when the rest of your outdoor broadcast equipment fails. Whether you’re looking for a lightweight and compact platform for boosting FM radio signals or you need high-performance communications capability for a larger area, Outdoor FM is here to help.
Other usages of outdoor FM antennas are for mounting on a jeep for deep jungle tours and adventure. FM antenna will give you an advantage over other radio listeners as it will provide beautiful music even in challenging conditions.
A simple solution for transporting your favorite music is an FM antenna. Almost everywhere in the world including in jeep touring groups use FM antennas. FM antenna will allow you to share your voice with other campers and hikers while complementing your appearance.
The most common item used in each branch of the military, as well as many other industries, is radio antennas. Antennas are attached to objects like vehicles, ships, buildings, or even people. With the advent of development, computers became smarter and more capable allowing for new and improved uses for these objects. Today, both amateur radio enthusiasts and military personnel rely on antennas to communicate with each other.
