　　How to install a mast antenna?

　　Installing a vehicle mast antenna requires striking a balance between stability and signal reception efficiency while avoiding damage to the vehicle's structure. The following is a general installation procedure, though specific details may vary slightly depending on the vehicle model and antenna mast type (fixed/telescopic):

　　1. Preparing Tools and Materials

　　Basic tools: Phillips screwdriver, wrench (matching the size of the base screws), utility knife (for removing old adhesive residue), alcohol wipes (for cleaning the mounting surface);

　　Supplementary materials: Waterproof sealant (optional, to enhance the base seal), replacement rubber gasket, masking tape (for protecting the vehicle's paint finish).

　　2. Pre-Installation Preparation

　　Determine the mounting location: Choose an unobstructed area, such as the front roof or the edge of the trunk lid, avoiding sunroofs or roof racks to ensure the antenna does not affect driving safety when raised.

　　Cleaning the mounting surface: Wipe the paint at the mounting location with alcohol wipes to remove oil, dust, and old adhesive residue. If replacing an old mast, clean any remaining screws and sealant from the original base.

　　Inspect the mast assembly: Ensure the base rubber gasket is intact (no cracks or hardening). For telescopic masts, test the telescopic function after installation to prevent sticking.

　　III. Core Installation Steps

　　Securing the Base:

　　Align the mast base with the mounting location and temporarily secure it with masking tape. Mark the screw holes.

　　Insert the base screws (usually 2-4) and tighten them evenly with a screwdriver (avoid overtightening any one screw to prevent deformation of the base). Ensure the base is securely attached to the vehicle body.

　　Sealing:

　　If the original base is missing the rubber gasket or the seal is deteriorating, apply a 2-3mm thick layer of waterproof sealant evenly along the gap between the base and the vehicle body. Let it sit for 10 minutes until it is partially dry.

　　Tighten the screws to completely seal the seal and prevent rain from seeping into the vehicle.

　　Installing the Mast Body:

　　Securing the Mast: Insert the mast directly into the base socket and turn clockwise to lock. (Some models require screws to secure the mast base.)

　　Telescopic Mast: First connect the bottom sleeve to the base, then extend the top antenna to the working length and tighten the retaining bolts.

　　Connecting the Signal Cable (if necessary):

　　Some masts require a car radio signal cable. Insert the connector into the vehicle through the pre-drilled hole in the base and connect it to the radio head unit (refer to your vehicle's service manual for wiring instructions).

　　IV. Commissioning and Inspection

　　Stability Test: Gently shake the mast to check if the base is loose or the screws are loose. Telescopic masts require a lock test.

　　Signal Test: Turn on your car radio or navigation system, tune to a frequently used channel, and observe signal stability. If there is noise, fine-tune the mast angle (within ±5°) to optimize reception.

　　Appearance Inspection: Ensure the mast is perpendicular to the ground (or installed at the designed angle), without any tilt, and that the sealant does not overflow and contaminate the paint.

　　Precautions: Avoid installation in extreme temperatures (hot or freezing), as the sealant's optimal curing temperature is 5-35°C.

　　Do not overtighten the screws to prevent cracking of the base or deformation of the paint.

　　If installing near an airbag or wiring harness, consult your vehicle's manual to avoid damaging components when drilling or tightening screws.
