Procomm 8" Stainless Steel Antenna Barrel Spring 3/8-24

This heavy-duty antenna barrel spring from Procomm is built to hold large antennas and flags while reducing stress at the mount point. Crafted from stainless steel for long-term rust resistance, the spring measures 8 inches in length and accepts standard 3/8-24 threaded antenna studs. It adds flex and shock absorption between the mast and antenna, extending equipment life and improving durability in mobile, marine, or exposed outdoor installations.

How does this spring protect large CB and two-way antennas?

The spring creates a flexible buffer that absorbs vibration and sudden impacts, preventing direct shock from transferring to the antenna base or coaxial connections. That flexibility lowers the chance of bent elements, broken mounts, or premature wear at the thread interface.

• 8" length provides significant travel for shock absorption
• Stainless steel construction resists rust in outdoor environments
• 3/8-24 thread fits standard amateur and CB antenna studs
• Coupling nut included for secure, easy mounting

Will this fit my antenna and mounting hardware?

The spring uses a common 3/8-24 thread size found on many CB, amateur and two-way antenna bases, so it pairs with most standard studs and mounts. Confirm your antenna's thread pitch prior to purchase to ensure compatibility.

• Thread size: 3/8"-24 (0.375 x 24) — standard CB/ham thread
• Includes coupling nut to join spring to existing studs
• Designed for heavy antennas and accessories such as flags or loading coils

How durable is the Procomm stainless steel design?

Manufactured from stainless steel, this barrel spring stands up to weather, salt spray and routine wear better than plated or soft-steel alternatives. The construction reduces corrosion and maintains mechanical integrity over years of service with minimal maintenance.

• Rust-resistant stainless steel for outdoor and marine use
• 2 lb weight signals robust, heavy-duty construction
• Solid coil design tolerates repeated flexing and load cycles

How easy is it to install and maintain?

Installation is straightforward: thread the spring onto the antenna stud or mount using the included coupling nut, then secure the antenna as usual. Maintenance is minimal—occasionally checking threads and removing debris keeps the spring functioning smoothly.

• Simple hand or wrench installation with included coupling nut
• Low-maintenance stainless surface resists buildup and corrosion
• Compact 8" length fits most installations without complex modification

Who is this for: The Procomm Super Heavy Duty stainless steel antenna barrel spring is ideal for radio hobbyists, mobile operators, truckers, marine users and anyone mounting large or heavy antennas and accessories. Choose this spring when you need a robust, corrosion-resistant shock absorber that uses the widely adopted 3/8-24 thread standard and provides years of reliable service with minimal upkeep.
