Firestik II FS Series CB Antennas

Top-Loaded: 5/8 wave: EZ ‘bare-hands’ tunable tip: voltage increasing coil design: unmatched, glass-fiber strand to resin ratio solid core: exceptional heat disapation rate for power ussers: static reducing, UV protecting covering.

If you took the proven features and performance of the famous “KW” series antennas and added a unique tuning mechanism to the top, you would own the equivalent of a Firestik II, “FS” Series antenna. Aside from the ease of tuning, the patented design broadens the antennas bandwidth to keep SWR lower over more channels. The upper coil extension also increases the power handling capability of the antenna. Contact us if you want to see the Firestik II anatomy. All “FS” antennas are compatible with autos, trucks, vans, motorcycles and ATV’s in a single antenna configuration when metallic ground plane is available. Or, they may be used in dual (co-phased) configuration on any vehicle made from any type of material. Like all CB antennas, the “FS” antennas should be fine-tuned (SWR) in their final mounting location. If you have ever tuned a non-tunable tip antenna, you will have a real appreciation for the “FS” antennas. To tune a “FS” antenna, you just pop-of the tip and turn the adjustment screw up or down as needed. All “FS” antennas exceed the requirements of any CB radio, new or old. Aside from the hi-performance loading coil that maximizes the transmit/receive functions of your CB, these top-loaded antennas will also receive the NOAA emergency weather alert and national weather broadcasts for radios with those features..

The “FS” antennas are 100% American made with 100% American materials. To maintain a balance between flexibility and ruggedness, we use a custom blended, glass fiber reinforced shaft. Each is wound with heavy insulated copper wire to prevent the oxidation and shorted windings often found on non-Firestik antennas. The tunable tip mechanism is made from rust-proof brass and has a rubber o-ring to hold the adjuster in place after tuning. Our 3/8″-24 threaded base has a tapered contact point that works especially well with Firestik mounts and accessories. The tapered “lug-nut” effect transfers stress away from the threads and reduces the possibility of vibration induced loosening of the antenna in its mount. Each antenna is covered with a static reducing, water-tight sleeve containing UV and pigment stabilizers. For peek performance we recommend that you use one of our 18-foot Fire-Flex coaxial cables with these antennas.

Note: These are ground-plane dependent antennas. They require a metallic counterpoise to perform properly. They are not suited for use on non-metallic (composite) vehicles or those with insufficient metal. They can be used to build a base station antenna if a ground-plane is provided. When used with a transmitter (versus a receiver) these antennas should be tested and tuned across the radio operating frequency. Using an untested, untuned antenna for transmitting can damage the transmitter’s circuitry.
