Car antennas come in many different sizes and shapes, from satellite radio antennas to GPS antennas, then from television antennas to terrestrial radio antennas. And not to mention, there are also cellular antennas.
Every single one of them is hardwired for receiving and handling a particular kind of signal. Of all these, the monopole whip type of antenna remains the most predominantly used for cars. These antenna systems can also handle FM and AM radio transmissions. Carry on reading the rest of the article so you can glean upon some of the most common types of antenna for cars.
Terrestrial Radio Antenna
Normally, when cars are shipped from the factory itself, they usually come out with an antenna already installed. The antenna is neither window-mounted type of antenna, a flat type, or a monopole whip antenna. For the longest time now, the whip antenna has taken the place of being used as the standard. They also come in many different styles, so there are variations one can choose from depending on one’s preferences and specific needs. As for the whip type of antennas, they are often stationary and rigid while others extend automatically the moment that the radio is shut down or turned on.
Even if the FM radio and the analog VHF television at one point in time run parallel to each other, and there are even instances also that they overlapped, the shift into digital format rendered the TV broadcasts in many different countries to run on Ultra High Frequency or UHF spectrum. If for some reason, you need to see a television broadcast inside your car, you will need a dedicated antenna for this purpose.
As earlier mentioned, there are several different kinds of antennas that are intended for car use. Included to this are the motorized satellite dishes, which is self-adjusting while the car is in transit or moving. For limousines, what they usually have instead are the iconic boomerang antennas. You can also use them in vans, RVs, and buses.
GPS Antenna for Navigation
GPS navigation antennas usually have a built-in camera. If you want to further increase their level of accuracy, you can do so by adding up an external antenna. At the same, it also lowers the chances of losing a satellite lock. In contrast to the other kinds of antenna intended for car use, where most of which are inclined to be passive, a GPS type of antenna is inclined to either become active or passive.
Cell Phone Car Antenna
Cell Phone car antenna comes in two forms:
- The first one is the antenna that you can physically hook up to your mobile device.
- The second type is the “signal booster”, they amplify and redirect the weak cellular signals such as active GPS antennas.
The former is more rampantly used than the latter. But there have been several developments and improvements in the world of cellular technology. Those developments worked to its advantage in such a way that they paved the way for these antennas to be hardwired into the very design of receiver devices such as mobile phones and cars.
Meanwhile, the so-called signal boosters remained stagnant in the regulatory area until such time that the 2013 FCC laid the needed guidelines for the groundwork of these devices.
