Carefully align the shark fin and press down firmly for at least 2 minutes to ensure adhesion. Frequently Asked Questions: Q1: Does the shark fin match the original car color? A1: The shark fin color closely matches the original car color. However, due to long-term outdoor exposure and environmental factors such as rain and snow, the original car color may have faded or changed slightly, so an exact match cannot be guaranteed. Q2: What is the radio signal performance after installation? A2: The antenna features purified copper connectors. Tested performance shows signal strength comparable to the original antenna. Q3: Is a small gap between the shark fin and roof normal? A3: The bottom of the shark fin has a slightly curved design. Most vehicles will have no gap; however, a small gap may appear on certain models. This does not affect functionality. Additional adhesive can be used if needed. Q4: What should be considered 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 before final installation. For better adhesion, warm the 3M adhesive with a hair dryer prior to application – this increases stickiness. Note: The adhesive has only one effective application, so ensure correct positioning. Press firmly for 3 minutes after placement and keep the area dry for 48 hours to allow full bonding.
