But having a good radio signal still depends on having a dependable antenna. Without it, your radio is nothing. A car antenna, which can be any electronic structure that is made to radiate or receive radio signals and other electromagnetic waves, is a must for every car.
You may say that your vehicle's stock antenna will do but it won't last that long, may be four to six years. They won't even last that long if you live near the ocean where the salty sea air can easily corrode it. A rusted antenna needs to be immediately replaced because, it won't work that efficiently. And if you're thinking of changing your antenna or even your antenna mast, be sure to get a power antenna or even a high-gain antenna for a sure signal. Also be sure to take note of the materials that were used on the antenna for these can make a big difference on the antenna's reception quality.
