Modern car antenna

Have you ever wondered about the length of car antennae? Why is this? Why did we use to use such long antennae? Were they all the same length? What changed? Why am I a dolphin reading the internet? Now, pretty much anything that conducts will act as a sort of antenna—tinfoil, a coathanger, some crutches—but in order to optimally capture that electromagnetic radiation and send it into a little box that converts it into electrical impulses that your speakers convert into physical compressions of the surrounding air and your eardrums convert back into other bioelectric signals and your brain converts into the sweet, sweet strains of Radar Lovethen that conductive whatever should be a certain length.

In the case of FM radio, the conductive thing can simply be a metal rod, and, ideally, its length should match the wavelength of an FM signal, which, at about Mhz, comes to around a wavelength of roughly ten feet. A ten foot antenna would be ridiculous. Mazda was even so pleased about moving to shark fin-style antennae that they made a whole web page just about that.

They came up with an idea to change bar-shaped parts to spiral coil, and used electronic substrate to make a receiver. You can see what the inside of one of these units looks like here, in this Reddit post from some poor guy whose antenna cover flew off his Sonata :.

Some are simpler inside, like this aftermarket antenna for a Cadilllac:. They were never great, but they were good enough, and arguably gave the cars a cleaner look. So, I hope this helps. There actually is a proper, ideal length for a radio antenna, and modern cars do all they can to hide that from you. The A. Shop Subscribe. Jalopnik Explains. Read on. Subscribe To Our Newsletter.

Got this to replace my factory antenna on my f Purchased this with the understanding there might be some reception loss. Haven't noticed any signal loss on the FM channels I usually cycle through. I live on the outskirts of Houston in Richmond, like 30ish miles from downtown where all the stations are located and the signal is the same as my factory antenna.

I work even further out and still no noticed reception issues. I have not tried every channel in the area and don't plan to but it is working like a charm and looks great. Installation is quick and it seats all the way down, so there is no gap present like some of the posted pictures regarding this issue. Add to cart. Dorman Help! This antenna replacement fit my Ford Flex perfectly. Jacobsen Washington state. This one however is very simple to install, that must be why it doesn't come with instructions, and works great!

The picture only shows an antenna but it comes with an attached 4 foot cable which sucked for me because my stock radio already had a the cable ran to the trunk. Bottom line works great, simple to install and cheap. Looks like original equipment. Great value and arrived when promised. Basic antenna that does exactly what I want it to do. I don't believe that spending a great deal more gets you any better reception. Manufacturers don't advertise gain, the measurement of an antenna receiving or transmitting signals.

If they did, I don't believe there would be a great deal of difference between the expensive and less expensive ones. Antenna shipped quickly and installed in about 1 minute. It looks great and has great size. I give it 4 instead of 5 stars because, for me, there definitely is a loss in reception.

I tried a dozen or so stations and there is a difference. Stations that had some static before, now have much more static. But most stations that I previously got good reception to I still have good reception to.

So I will keep it and use it. See All Buying Options. I ordered this antenna based on customer reviews and it works great. I replaced the original one on my Mazda 3 and the reception is as good as the original. I use an FM transmitter in my car and I haven't had any problems.Automotive antennas have evolved since their introduction in the s. Once tacked on as optional equipment, they are now designed into the car as an indispensable accessory.

Several different approaches have been used to improve performance while making the antenna attractive, including embedded windshield versions and electric hide-away styles. In the s, car antennas were incorporated into the radio body, as most stations were in the AM band, which required a ferrous core receiver antenna.

The lack of bandwidth competition and general radio noise in the s also meant that stations could be picked up for a long distance without external receiver antenna hardware. With the advent of FM bands, the antenna was required to be a straight section of wire bolted onto the body of the car at any convenient location.

FM, or frequency modulation, was a different way to broadcast a radio signal. While a clearer signal would propagate further distances, the equipment became more complex. The antenna was still a simple length of hard steel or alloy wire mounted to the body by drilling a hole for the mounting hardware. But the primary antenna had to have a rubber gasket where it contacted metal to prevent it from grounding to the body. As luxury car manufacturers sought innovative ways to hide the external radio antenna seen as an eyesorethey began installing electrical motors that would extend the antenna when needed.

A motor pushes a plastic or metal driver through a series of interlocked metal tubes, which would then be used for radio reception once extended. In the s, General Motors got creative with radio antennas, pressing small wires into the windshields of their products to provide radio reception.

These wires were placed into a "T" formation, with two wires coming up through the center, then branching out to each side. While these windshield antennas gave decent directional reception, replacing or repairing them was expensive.

Most manufacturers standardized antennas in the s so that they were not much more than metal poles for cheap vehicles and electric-powered units for expensive models. Antennas found on most 21st century cars use the same basic principle as the metal pole versions, but they are more compact and stylish.

They have a small strand of wire, cut to the same length as a metal pole, but are wrapped into a coil rather than stretched out. This allows for a much shorter unit with the same capabilities. Citizens' Band radios have been using this concept since the s to extend range, but only at the turn of the century has it been applied to general radio reception for cars.

These smaller antennas are set at rakish angles to improve the car's appearance, although such placement really does not improve reception. As new technology comes onto the field, AM and FM radios are soon to be phased out for better methods of communication. While the merits of keeping the media are numerous, satellite broadcasting has become a popular replacement. The satellite radio antennas are even smaller than modern radio antennas and resemble small, black plastic squares.

As they are not used to receive terrestrial transmission, they do not need to be long and upright; they only need to be pointed at the satellite and grounded away from the vehicle.

As this antenna is much easier to hide, the classic metal pole antennas that became the mainstay of automobiles during the last century will disappear.

There, backed by his father's investment, he conducted a short-range telegraphy experiment that would slowly transform into the first commercially viable, long-range radio communications system. The young polymath adapted his wireless telegraph to transmit signals produced by the carbon microphone designs that Thomas Edison and Emile Berliner had invented. Widely considered the father of radio communicationsMarconi would go on to perform the world's first transatlantic transmission in Engineers spent the next 20 years developing radio technology robust enough for widespread use, and a large number of great minds contributed in different ways the birth of American radio broadcast.Also, to some of us, it gets very boring driving without some music.
