The ""FL"" Series antennas are the performance leader of lightweight top-loaded CB antennas, Each is approximately 40% lighter than the equivalent length Firestik II antenna, From the perspective of mount stress, the lighter materials and reduced wind drag of the ""FL"" antennas reduces stress by more than 60%, A 4-foot FireFly will easily perform on a mount that is designed for antennas 3-foot or less, At the top of every ""FL"" antenna you will find FireStik"s patented tunable-tip, Besides making tuning a snap, the design broadens the antennas bandwidth and increases its power handling capabilities, All ""FL"" 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, All ""FL"" antennas exceed the requirements of any CB radio, new or old, These top-loaded antennas will also receive the NOAA emergency weather alert and national weather broadcasts for radios with those features, Mount Type: 3/8 inch x 24, Length: 48 Inches, Frequency Range: 26-30MHz, Frequency Type: CB Radio, Load Position: Top, Antenna Type: Fiberglass, Power Rating: 200 Watts, Mount and/or Cable Included: No, Termination: 3/8 inch x 24, Lightweight, Easy-tune "bare-hands tunable tip", High-performance coil design, Flexible fiberglass tube, SKU: CBDST0767
