Internal car antennas: These car antennas are fitted inside the car, on the dashboard, windshield or the trunk of the car. This effectiveness of the reception of this antenna is not on par with other antennas. Several internal antennas are needed to improve the quality of reception of radio signals.
External car antennas: These antennas, in the form of telescoping metal or fiber-glass poles, are attached to the exterior of the car especially on the hood, rear or the roof of the car. The quality of radio signals received by these movable antennas, is better than those that are fitted internally. Though the main disadvantage of this antenna, is that it is prone to accidental damage.
Power car antennas: These are antennas that are designed to overcome the weakness of external car antennas. These are placed in a compartment or housing attached to the exterior of the car. When the car ignition is switched off, they don’t hang in the air like how external antennas do, and hence, are not prone to damage. The power car antenna mast is ejected or lowered, by an electric motor connected to it. When the car ignition is activated to ‘on’ by inserting and turning the key in it, the electrical motor controlling the antenna is activated and propels the power car antenna mast up, and out of it’s housing. The power car antenna when ejected, can receive radio transmissions. When the ignition switch is set to ‘off’, the electronic control signals the electrical motor, to lower or collapse the antenna mast. Thus, the power car antenna is safely tucked inside the protective compartment, when it is not in use.
Satellite dish: Small, round satellite dishes are used as antennas, to receive satellite signals, which are then carried to the receiver by wires from the antenna. The satellite radios receiver, are fixed to the dashboard of the car.
Global positioning system (GPS): Navigating, using the GPS navigation system is the latest trend. Special car antennas are used to capture navigation signals from the global positioning system. Some of the antenna units can receive navigation and radio signals, from satellites. Nowadays, a computerized car audio system is available, that can handle audio signals for the phone, radio signals from satellites and navigational videos from that global positioning system.
How a Power Car Radio Antenna Works
The power car radio antenna mast has a nylon cord attached to its base. This cord is reeled in by a reversible electrical motor connected to the antenna, to lower or eject it. When the power car radio mast is fully extended or collapsed, the motor stops reeling in or out. For this purpose it is provided with two switches. Electrical power to the antenna is supplied using a wire connected to it. Another wire leading from the radio, and connected to the antenna, acts as the actuator. The whole power car radio antenna assembly is mounted firmly, so that it cannot move when it is actuated to complete the circuit. It reduces wear and tear of the electronic components that comprises of a significant portion of the car parts, and prolongs the life of the system. A fuse aligned with the power transmitted to the antenna, prevents the chances of a fire occurring, due to overheating of the motor, in case it fails to stop while its reeling in or out.
Radio signals received by the antennas of power cars are fed to an amplifier, which amplifies the signal and feeds it to the speakers. Antenna boosters attached to the antenna, improves the reception of signals. Replacing a broken power car antenna is not a big deal. These parts are easily available on Internet outlets and also through dealers or local retailers.<!– From http://www.buzzle.com/articles/power-car-antenna.html –> <!– google_ad_section_end –> The new phenomena from the automobile industry, air powered cars have stunned auto analysts and car lovers worldwide. With the process of making a car, which uses air as a fuel to run has brought smiles to many faces around the world. Since the threat of global warming has been exposed inventors from all around the world are in the process of discovering some new hybrid cars which run on natural fuels and not on fossil fuels. Gasoline as we know is going to finish someday, plus it also gives out harmful gases which has caused many respiratory diseases and is also the prime concern of global warming. To minimize the use of gasoline, many car companies have designed some electric cars to help save the planet.
Automobile companies all around the world are in the process of making a successful air powered car, which runs smoothly, gives a great performance and is also light on the common man’s pocket. To know how these green cars are helping save the environment have a look at hybrid cars and the environment.
Compressed Air Powered Car
A compressed air powered car is fitted with a motor which uses compressed air as fuel. The dream of a compressed air car seems too good to be true, if engineers can come up with an air powered car engine then why use anything else? Air is in abundance and the best part is that air is free. The first air powered car that would be built will have air compressors in them. After a long drive you can take your air car in the garage and recharge it. The compressor will use all the air gathered around your car to fill itself up, this would take some time to fill up. If the air powered car becomes popular, we might be able to see a lot of air refueling stations instead of gas stations. The air cars will use a compressed air engine developed by a French company. This engine will have tanks that would hold the required quantity of air. Many famous automobile companies have also come up with the concept of hydrogen cars for a green environment.
Air Powered Car Project
Due to the stir caused by the air powered car in recent times, a US automobile company has declared that it is going to come up with an air powered car in America in the late 2010. It has also finalized a mutual partnership with an automobile company in Luxembourg which was the pioneer in air car technology. Car manufacturing plants have already been started assembling cars, they hope to come out with 10,000 air powered cars each year. The American company has also given its detailed attention to the price of the car. They are pricing it at a very economical range of $17,800. The American air powered car would be six seater, 75 hp power and can travel up to 1000 miles with just a tiny fill of air. To have a clearer idea on such green cars, have a look at hybrid cars facts. Schools across the world have been giving out projects to kids on how to build something that would save the environment, have a look at how to build an air car.
The French engineers have also started the process of making the first French air powered car which is expected to hit the roads of France soon. Automobile engineers in France have designed a less consuming and less polluting engine that runs on compressed air technology. It’s a zero emission vehicle, with an engine that is safe, quiet, and has a speed of 110 km/hr. Air powered car was a concept that was very popular in Europe but due to some safety and efficiency reasons they were discontinued. But the French air powered cars have undergone some stringent checks, so there is hope that we can see some air powered cars zooming on French roads soon.
