A1: The shark fin color closely matches factory colors. However, due to long-term outdoor exposure and environmental factors such as rain and snow, original car paint may have faded or changed, making an exact match difficult. Q2: What is the radio signal performance after installation? A2: This antenna features purified copper connectors. Tested performance shows signal strength comparable to the original antenna. Q3: Is it normal to have a small gap when installing on the roof? A3: The bottom of the shark fin has a slightly curved design. Most vehicles will have no gap, but a small gap may occur on certain models. This does not affect functionality. Additional adhesive can be used if needed. Q4: What should I keep in mind during installation? A4: Clean the area around the antenna base thoroughly, ensuring it is free of water and dust. First, connect the cable to the base and test the radio signal. Once confirmed, proceed with installation. For better adhesion, warm the 3M adhesive with a hair dryer before application to increase stickiness. Note: There is only one chance to apply it, so ensure correct alignment. Press firmly for 3 minutes after placement and keep the area dry for 48 hours.
