Radio Antennas

Radio antennas?

Why are handheld radios(FRS, CB, Amateur) antennas just one wire? How can that work to receive and transmit if it’s just one wire? I mean the antenna should be TWO wires, just like the antennas on the big stations, or the TV antennas. It should be a closed circuit((- and +) OR (- and ground)?).

They do have 2 wires. Internally to the radio there is a ground.

Now for you next question:
buy your self a Discone antenna and a good quality 50ohm coax
You need to adjust you SWR . You also need to know what band you are on. You can find that out by going to the manufactures wed site
If your house is aluminan sided that will cut down on you reception/transmission. When your standing on the roof you are outside of the box (so to speak) so the siding isn’t causing the problem.Mount the antenna on the chimney and set your SWR.
this should help.

Good luck

Satellite is often considered one of the biggest improvements in broadcasting since the introduction of the FM band. Satellite radio is also called the subscription radio or pay-radio because it is available only through subscription to one of the satellite radio providing companies.

Satellite follows a concept similar to cable television, providing a wide range of programs that are not available in the traditional FM or AM format for office.

Satellite uses satellites to deliver radio programs to subscribers. The radio signal is transmitted from earth stations satellite communication, which then redirects the signal to the satellite radio receivers. The radio signal is transmitted by communication satellites to an area much larger than traditional terrestrial radio antennas.

For example, the satellite is available to the entire continental United States. Radio Satellite is available in most parts of the world through the services provided by companies like WorldSpace (in Europe, Asia and Africa), Sirius and XM Radio (in Latin North).

The received signal using the satellite radio is digital, which means that it is always clear and free of static, which is one of the great advantages satellite radio. Another great thing about satellite is that it is almost completely commercial-free.

To start listening to satellite radio will have the real satellite (also known as tuner or receiver), a satellite antenna (which is often incorporated into the satellite radio) and a subscription service you choose. There are several types of satellites to choose from.

One of them is the dedicated car or home radio, which played through your vehicle or stereo. A second option is the plug-and-play radio, which can be used in your car and at home, paying a single subscription. The third option is the portable radio, which has rechargeable battery, a built in antenna and can be heard wherever you go using headphones.

The signals from different satellite radio companies are proprietary, which means you need different hardware to receive, decode and playback, depending on their subscription. Each satellite receiver has its own serial number called Radio ID.

When you receive your subscription, you'll also receive a code activation of its receptor. Besides the actual radio programs via satellite transmits metadata that contains the name of the artist, song title or program, and the name of the channel. This makes it easier for you to decide which channel to listen to and what program to choose.

Satellite's radio services provide subscribers with more than 100 programs that vary in content of rock and jazz to rap and classical music. But the utility goes far beyond Satellite listen to your favorite music without the interruption of those annoying ads.

Satellite also offers exclusive sports programs, shows cultural and educational, news and talk shows. Some of the celebrities who have spent their free radio satellite radio include Howard Stern, Opie and Anthony, Bob Edwards and Martha Stewart. Unlike terrestrial radio, satellite is not affected by bad weather or even calamities.

At first, many wondered why they should pay for radio if you can get for free. However, satellite radio attracts more and more people every year because of its great advantages: non-commercial a broad scope, thematic programs and exceptional sound quality.
