Antenna spring also called whip antenna spring mount is used at the bottom of the vehicle antenna to protect the antenna from vibration and sway when driving, and ensure stability-keeping the antenna upright. Yisen Spring produces various antenna springs, including cylindrical and barrel shape (smaller diameters at both ends and a larger diameter in the middle) which offer higher space utilization, resistance to resonance and enhanced stability. We provide multiple customized sizes, surface treatment options and full inspection including spring force testing, bending testing and rust, corrosion, and UV resistance testing.
Antenna springs are usually composed with two parts-the end caps and the middle spring, it can be easily locked into the metal base of a vehicle. Yisen Spring’s antenna springs are designed and developed to withstand harsh environments. Based on different scenarios and antenna length requirements, antenna springs can be categorized to light duty, medium duty and heavy duty antenna spring, suitable for different applications such as off-road vehicles, ships, and communication equipment.
Yisen’s spring mount can handle heavy antennas, providing greater stability at highway speeds than other normal antenna springs. Every antenna should be equipped with an antenna spring base.

Every antenna should be equipped with an antenna spring base.
Designed for smaller, lightweight, and highly flexible whip antennas, these springs provide excellent responsiveness to minor vibrations. With a wire diameter ranging from 2.5 mm to 3.8 mm, they are ideal for standard passenger cars, compact communication devices, and applications where minimal mechanical resistance is required to keep the antenna upright.
Engineered for a balanced blend of flexibility and strength, medium-duty springs feature a wire diameter from 4.0 mm to 7.5 mm. They are perfectly suited for mid-sized fiberglass or steel antennas used on SUVs, light trucks, and utility vehicles, ensuring the antenna stays stable at highway speeds while safely flexing when hitting overhead obstructions like garage ceilings or low-hanging branches.
Built for maximum durability in extreme environments, heavy-duty springs utilize thick wire diameters from 8.0 mm to 10.0 mm to handle massive, heavy-duty tactical or marine antennas. These rugged spring mounts provide superior resistance to intense wind load, harsh vibrations, and violent impacts, making them the top choice for off-road vehicles, military communication equipment, and maritime vessels.
This is the most common application. On off-road vehicles, SUVs, trucks, and agricultural machinery (e.g., tractors), drivers often install mobile radios, CB radios, or GPS antennas. When driving through dense woods or rugged terrain, tall antennas can easily hit low-hanging branches or clearance barriers. Heavy-duty spring bases absorb these impacts, allowing the antenna to flex and snap back without breaking the antenna or damaging the vehicle mount.
Military armored vehicles, tactical jeeps, and mobile command vehicles require high reliability. Their HF/UHF tactical communication antennas must stay intact while traversing battlefields or harsh environments. Military-grade spring bases, made of high-strength and corrosion-resistant stainless steel or alloys, ensure that the communication system remains operational under high-speed movement and severe vibrations.
On small to medium-sized boats, speedboats, fishing vessels, and offshore patrol craft, VHF and GPS antennas endure continuous mechanical stress from pounding waves and rough seas. Spring bases mitigate stress fatigue caused by wave impacts. Furthermore, with specialized surface treatments (like electropolishing or chrome plating), they can withstand long-term exposure to salt spray and harsh marine environments.
