Car antennas are considered a significant automotive accessory as these are able to provide an uninterrupted transmission of wireless signals and radio waves in your vehicle. People often look for a replacement when their car antennas get damaged or become non-functional.
Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. Radio waves are electromagnetic waves which carry signals through the air (or through space) at the speed of light with almost no transmission loss.
How do I disconnect my antenna?
Why there is an antenna on the roof of the car?
This has an obvious reason, because the roof of a car is the high above ground and unobstructed. This provides a good reception into every direction. Mostly, omni directional reception is required anyway, so placing the antenna on the roof is one of the best options for most of the vehicles, except convertibles.

What is the purpose of a power antenna?
A power antenna is an electrically motorized automotive radio antenna that raises and lowers either manually with a dash-mounted switch or automatically by turning the radio on or off.
How does a car antenna work?
The antenna on your car will pick up the magnetic energy that a transmitter transmits and sends it to your vehicle’s receiver. Consequently, it generates tiny electric charges. The receiver then isolates and amplifies the specific radio waves that are of interest to you.
How do I test my car antenna?
Connect one lead from the meter to the tip of the antenna, and the other to the radio pin — the piece at the end of the antenna cable that fits into the radio. The reading should be low, usually under 5 ohms; that means a good electrical connection between the tip of the antenna and the radio pin.
