Comparison Insights: Prostick vs. Francis
When deciding between these excellent choices, the primary difference comes down to power and intended use.
The Prostick series (2′, 3′, and 4′) is engineered for raw durability and high wattage handling. All Prostick models reviewed here handle an impressive 1000 Watts, making them ideal if you ever plan to run an external amplifier or simply want the most robust internal wiring available. The Prostick models are the clear choice for professional drivers or off-roaders due to the VibraSorb anti-breakage technology.
Conversely, the Francis 300-CB22 models are focused on style and vehicle integration. Rated at 100 Watts, they are perfectly sufficient for standard 4-watt CB operation but lack the overhead for amplification. The defining feature of the Francis antennas is that they are AM|FM ready, allowing them to serve as a dual-purpose antenna and simplifying vehicle wiring. If your installation space is limited to a single antenna mount, the Francis offers superior integration.
Length is also a critical factor: the 4-foot Prostick provides the longest range, while the 2-foot Prostick offers the most clearance. The 3-foot Francis and 3-foot Prostick offer a great middle ground, balancing range and accessibility.
Final Verdict on the Best Fiberglass CB Antenna
Choosing the best fiberglass cb antenna depends entirely on your vehicle and goals.
For Maximum Range and Power: If you drive a large truck, run long hauls, or plan on utilizing high-wattage amplification, the Prostick 4` Foot Fiberglass 1000 Watt is the undisputed top contender. It provides the height needed for superior transmission and the durability to handle rough conditions.
For Optimal Balance and Clearance: The Prostick 3` Foot Fiberglass 1000 Watt is the best general-purpose option, offering robust 1000W support in a size that works well for co-phasing setups on pickups or general SUV mounting.
For Style and Vehicle Integration: If you only require standard 4-watt operation and want your antenna to perform double duty while looking exceptionally clean, opt for the Francis 300-CB22B Black 3 Foot Hot Rod CB Antenna. Its AM/FM capability provides unmatched convenience.
Common Questions About Best Fiberglass CB Antenna
Do I need to tune a fiberglass CB antenna?
Yes, absolutely. Even though many antennas, like the Prostick series, are “factory tuned,” this is only a broad tuning. Every antenna mounted to every vehicle requires fine-tuning using an SWR (Standing Wave Ratio) meter. Factors like mount location, cable length, and surrounding metal affect performance, so checking and minimizing SWR is crucial for achieving the best performance and protecting your radio.
How does the length of the fiberglass antenna affect my range?
Generally, the longer the antenna, the better the performance and potential range. A longer antenna is closer to a “full-wave” antenna, making it more efficient at radiating and receiving signals. For example, a 4-foot antenna will usually outperform a 2-foot antenna because it captures and transmits the radio waves more effectively.
What is the advantage of using a fiberglass mast over a metal whip?
Fiberglass antennas are often preferred for their flexibility and impact resistance. Unlike rigid metal whips that can snap or bend permanently when striking a low-hanging branch or sign, fiberglass masts flex and absorb the impact, returning to their original shape. This makes them significantly more durable for off-road driving or high-vibration applications.
Is a 1000 Watt rated antenna necessary if my radio only puts out 4 watts?
A 1000 Watt rating means the antenna can safely handle that level of power without overheating or failing. While your standard CB radio only transmits 4 watts, using a high-wattage antenna provides a massive safety margin if you ever decide to install a linear amplifier. More importantly, it often indicates superior build quality of the internal wiring and connections, which translates to better efficiency and longevity even at 4 watts.
Can I use two fiberglass antennas (co-phasing) on a single vehicle?
Yes, many truckers and enthusiasts use two antennas in a co-phased arrangement, typically mounted on the mirrors or rear of the cab. This requires a specific co-phasing harness and two identical antennas (like the 3-foot Prostick models). When done correctly, this setup can provide an improved radiation pattern, particularly in the forward and rear directions.
What is a “ferrule” and why is a brass one important?
The ferrule is the threaded base connection point of the antenna that screws into the mount. A high-quality material like nickel-plated brass (as used in the Prostick and Francis models) is crucial because it resists corrosion, ensuring a solid, stable electrical connection between the antenna mast and the mount, which is vital for maintaining a low SWR.
