Show original supplier description

The Firestik FS4-BLACK is a 4-foot CB antenna engineered for reliable communication. Its top-loaded, 5/8 wave design incorporates a voltage-increasing coil for enhanced performance. The antenna features an EZ 'bare-hands' tunable tip, allowing for straightforward SWR (Standing Wave Ratio) adjustment without special tools. This patented design broadens the antenna's bandwidth, helping to maintain lower SWR across more channels and increasing power handling capability. The antenna is covered with a static-reducing, UV-protecting, and water-tight sleeve. It utilizes heavy, insulated solid copper wire for its windings, preventing the oxidation and shorted windings common in other antennas. The antenna base features a 3/8"-24 thread with a tapered contact point designed to work seamlessly with Firestik mounts and accessories, providing a secure connection that resists vibration-induced loosening. All FS series antennas are 100% American-made and factory bench tested for resonant frequency and quality. This model is rated for up to 900 watts. Like all transmitting antennas, the FS4-BLACK must be tuned (SWR) in its final mounting location after installation.
