Exterior Antennas for Cadillac SRX
Antennas are needed to make the radio work in your Cadillac SRX. The type and style of the antenna are different for the type of signal you want to receive. If you are going to be working on repairing, replacing, or upgrading the antenna on your Cadillac SRX, here are some things you should know about how they work and the different types that are available to use in your SRX SUV model.
How do car antennas work?An antenna serves as a magnet to capture radio waves sent into the atmosphere by a transmitter. The radio waves emit electromagnetic radiation that is attracted to the metal in the antenna. The waves attach themselves to the antenna and move to the radio or television in the Cadillac where they are transformed into sound and video for you and your passengers to enjoy while youre behind the wheel of your Cadillac vehicle.
What types of antennas are there?Antennas can be divided into three groups: standard, digital, and satellite. Standard antennas are used to pick up AM and FM radio waves while the digital ones are used for television and high-definition radio stations. Satellite antennas are used primarily for paid subscription services. Many Cadillac owners use a combination of standard, digital, and satellite antennas on their cars.
What is the standard/digital type of antenna?Standard and digital antennas work the same way, and both can be located either on the outside or inside of the Cadillac. The antenna typically consists of a long metal rod screwed into the top of a base. The base collects the signal and sends it to the radio via a cable.
What is a satellite antenna?The satellite antennas look like shark fins and are always located on the outside of the Cadillac SRX. The satellite signals cannot penetrate the metal of the car well. These antennas are used to capture feeds coming from satellites rotating around the earth. Satellite antennas are used for those who use paid subscription services like OnStar and Sirius Radio Network.
Do you need an HD antenna for HD radio?A standard antenna is typically used for HD radios, but you can use a digital one just as well. Radio transmitters send out both analog and HD signals of the programming content. HD radios accept both types of signals and will use whichever signal is the strongest to emit what is playing on the radio. However, if you are using a digital television in the car, you’ll need a digital receiver system since television stations only broadcast programming using digital technology.
What kind of parts are available?The antenna parts come separately or in kits. There are original GM OEM parts, aftermarket, and used parts available. Not all the parts are universal, so you have to make sure you know what will fit your Cadillac SRX before getting any replacement parts.
