Comet B-10 Mobile VHF/UHF Vertical Antenna – High-Performance Vehicle Antenna for Ham, CB, and Scanner Radios

The Comet B-10 is a versatile antenna designed for multi-band use, covering not just the CB frequency range (often usable with adequate tuning) but also the VHF and UHF bands favored by Ham radio operators and scanners. Its primary strength lies in its high-performance design across these higher frequencies, offering strong signal reception and transmission. While primarily a Ham antenna, its durable, professional-grade construction ensures reliable use across different mobile communication needs.

Key features that stand out:
– Multi-Frequency: High-Performance VHF/UHF Antenna (secondary use for CB).
– Quality Construction: Made with precision materials for long-lasting use.
– Installation: Quick plug-and-play mounting with minimal tools required.
– Trusted Brand: Manufactured by Comet, known for professional-grade performance.

Pros:
– Extremely versatile for multi-band operators (Ham, CB, and Scanner).
– Durable construction holds up well against highway vibrations and elements.
– Professional quality ensures consistent signal strength.

Cons:
– Tuning for the specific 27MHz CB band can be tricky, as its primary focus is VHF/UHF.

Best for: Ham radio operators who occasionally use CB and require a high-quality, versatile mobile antenna.

Expert Opinion: This is a fantastic general-purpose antenna, but CB-only operators should opt for a dedicated CB antenna like a Wilson or Francis for guaranteed low SWR on the 27 MHz band.

Comparison Short Insights

When evaluating the best performing mobile cb antenna options reviewed here, the biggest differentiator is power handling versus size.

If you are running a high-wattage radio setup (over 100W), stick exclusively to the heavy-hitters: the Wilson T2000 series (3500W) or the Wilson T5000 (5000W). The Wilson T5000 has the highest power rating and is built for maximum distance.

For temporary mounting, there are excellent magnetic options. The Stryker SR-A10MM dominates in terms of power handling for a magnet mount (10,000W), making it suitable for amplified mobile setups. In contrast, the Nagoya CB-72 is the best choice for quick, hassle-free installation for standard 4-watt CB units, featuring low SWR right out of the box.

For drivers needing a balance of durability and a slightly shorter profile, the 3-foot Francis 300-CB22B fiberglass antenna is highly recommended. Fiberglass is often more resilient to low-speed bumps and snags than rigid stainless steel whips.

Finally, remember that height matters. The Wilson 305-497 T2000 with the 10-inch shaft provides a distinct performance advantage over the 5-inch shaft versions, especially when mounted low on the vehicle body.

Final Verdict: Choosing Your Champion CB Antenna

Selecting the right antenna depends entirely on your needs: power, portability, and vehicle type.

The Range King (Best Overall Performance): The Wilson Antennas 305550-5 T5000 takes this crown. Its massive power handling and optimized design ensure maximum clear communication distance, making it the top choice for long-haul professional use.

The Magnetic Mount Powerhouse: The Stryker SR-A10MM Magnetic Mount offers unparalleled power capability in a non-permanent mount. If you need 10-meter capability and serious wattage without drilling, this is your unit.

The Reliable Workhorse (Best Value for Truckers): Any antenna in the Wilson T2000 Series, particularly the black 305-492, provides the ideal blend of high power handling (3500W), proven durability, and excellent efficiency for the majority of professional drivers. It’s the standard for a reason.

The Best Budget/Beginner Option: The Nagoya CB-72 High-Performance 28″ CB Antenna Kit is the easiest way to get high-quality communication quickly and cheaply, requiring zero fuss and no manual SWR tuning.

Common Questions About best performing mobile cb antenna

How does SWR affect the best performing mobile CB antenna?

SWR (Standing Wave Ratio) is the measurement of how efficiently your antenna and cable system transfers radio energy from the transmitter. A lower SWR (ideally 1.5:1 or below) means your antenna is radiating most of the signal, maximizing range and protecting your radio’s internal components. A high SWR (2.5:1 or above) indicates a poor match, meaning much of your power is reflected back, which can cause severe radio damage over time.

Is a magnetic mount as effective as a drilled mount?

A magnetic mount can be very effective, provided it has a strong magnet (like the 5-inch Stryker) and is placed correctly on a large, flat metal surface (the vehicle roof is ideal). However, a drilled (or permanent) mount generally offers a better, more consistent ground plane connection to the vehicle chassis. This superior ground connection typically results in slightly lower SWR and slightly better overall radiating efficiency than the average magnetic setup.

What is the advantage of a center-loaded antenna versus a base-loaded or fiberglass whip?

Center-loaded antennas, like the Wilson T2000 and T5000, place the loading coil near the center of the radiating element (the whip). This location is generally considered the most efficient for mobile antennas, offering superior bandwidth and power handling compared to base-loaded coils, which are placed at the very bottom. Fiberglass whips are highly durable and discreet but typically cannot handle the same power levels as the large, steel center-loaded designs.

Do I need a spring for my mobile CB antenna?

A spring is highly recommended for any full-size mobile CB antenna, especially for large whips like the 49-inch Wilson models. The spring acts as a shock absorber, protecting the antenna whip, the mount, and the vehicle body from damage caused by overhead strikes (low branches, garage doors, etc.) or high winds. It does not negatively affect the performance of the best performing mobile cb antenna.

How important is the cable (coaxial) quality when maximizing performance?

Coaxial cable quality is crucial. Poor quality or improperly routed cable can introduce signal loss and high SWR, completely negating the benefits of a powerful antenna. You should always use high-quality, low-loss cable (like RG-8X or RG-58A/U for shorter runs) and ensure the length is sufficient but not excessive, avoiding tight bends or kinking, which can damage the shielding.

Can a dual-band Ham antenna, like the Comet B-10, truly be one of the best performing mobile CB antenna options?

While the Comet B-10 is an excellent multi-band VHF/UHF antenna, it is not optimized for the 27MHz CB band. If your primary communication is CB, a dedicated CB antenna (like those from Wilson or Francis) is the best performing mobile cb antenna because it is specifically engineered and tuned to resonate efficiently at 27 MHz, ensuring maximum range and lowest SWR without complex modifications.
