The antenna supports LTE, 4G, and 3G, providing robust performance for a variety of cellular needs.

Its high efficiency and low-profile design make it an ideal option for in-vehicle installation without taking up much space or being obtrusive. The antenna comes equipped with a 10 ft LMR100 cable and an SMA-Male connector, allowing for flexible placement and easy connection to weBoost cellular boosters. The product dimensions of 5.75 inches in length, 3.5 inches in width, and 1.25 inches in height, along with a lightweight of 3.68 ounces, add to its ease of installation and portability.

The kit includes useful installation accessories like an alcohol wipe, Velcro adhesive strip, and an additional adhesive strip, simplifying the setup process. Manufactured by Wilson Electronics in the USA, the antenna is built to last and withstand the rigors of in-vehicle use. It is best suited for those who already use weBoost cellular boosters, as it is specifically designed to complement them.

The Black K40 K40BCMAX is a solid choice for truck owners looking for a small yet powerful CB/10-meter antenna. It operates within a broad frequency range from 26 MHz to 30 MHz, making it versatile for various communication needs. The open helical coil design ensures a wide bandwidth and promotes efficient cooling, which can be beneficial for consistent performance.

The tunable 48-inch stainless steel whip allows for precise adjustments to achieve a great SWR match, even outside of normal CB bands, adding to its flexibility. The antenna’s construction is robust, featuring anodized aluminum that is both lightweight and corrosion-resistant, along with chrome-plated brass ferrules and a stainless steel stud for secure mounting. These materials ensure the antenna can withstand harsh environmental conditions, contributing to its durability.

However, the product's length might be a drawback for those who prefer a more compact antenna. If you’re in need of a reliable antenna with a good balance of performance and durability, the K40 K40BCMAX is worth considering.

The weBoost 311229 4G-OTR Trucker Edition Antenna is designed specifically for trucks and large vehicles traveling through areas with weak cellular signals. It’s an omnidirectional antenna, meaning it picks up signals from all directions, which is great for moving vehicles like semi-trucks. The antenna extends from 7.5 to 40 inches, offering flexibility in length to improve signal reach depending on your setup. This size is reasonably compact for trucks, balancing performance and easy mounting.

Durability is a strong point here: it meets military-grade (US Military 810H) and IP66 standards, so it’s built to resist tough weather, dust, and vibrations commonly faced on the road. This makes it reliable for long hauls and rough conditions. The package includes a 3-way mount, spring base, and a long 16-foot cable, which simplifies installation on different truck types and helps avoid signal loss.

The antenna is universally compatible with all US cellular carriers and supports multiple network types, including 5G when paired with a compatible weBoost booster (sold separately). It requires connection to a booster system to amplify signals effectively. While the antenna offers good gain for better reception, the actual signal improvement varies with the booster used and the location. Installation involves some basic setup, so it may take time to properly mount and tune the antenna. This antenna is a solid choice for truckers or fleet operators who want to enhance cellular connectivity in remote or poorly covered areas, offering rugged build quality, flexible length, and universal compatibility when used with a compatible booster system.
