10 Best GMRS Antennas 2025 in the United States

The Retevis GMRS Base Antenna is designed to enhance radio communication for GMRS frequencies ranging from 462 to 467MHz, making it compatible with various GMRS radios like Retevis, BTECH, Midland, Motorola, and Wouxun. With a high gain of up to 7.2dBi, this antenna ensures clearer and more stable communication, which is especially beneficial in remote locations. The low SWR (Standing Wave Ratio) of less than 1.5 further contributes to its efficient performance by minimizing signal loss.

The antenna is built from heavy-duty fiberglass and alloy connectors, enhancing its durability and weather resistance, making it suitable for outdoor use. The three-section design, connected by copper rods, helps reduce power loss and improve reception and transmission capabilities. However, potential buyers should be mindful of the installation environment as tall buildings or metal obstacles can affect performance.

At 37 inches in length and weighing around 2.8 pounds, the antenna is relatively lightweight and manageable. Despite these strengths, it's important to note that some installation environments may impact its effectiveness.

The Retevis GMRS Mobile Antenna stands out in the GMRS antenna category due to its impressive specifications and features. With a frequency range of 462-467MHz and a gain of 6.5dB, it effectively enhances communication distances, making it an excellent choice for users needing reliable radio connections, such as campers or off-road enthusiasts. Its length of 48.2 inches provides good height for extended range, while the durable fiberglass construction ensures it can withstand various weather conditions, contributing to long-term use.

One notable feature is the spring base, which allows the antenna to flex during driving, reducing the risk of damage from vibrations. The included 16ft RG-58U coaxial cable and mounting hardware make installation straightforward, even for those not particularly tech-savvy. The antenna's compatibility with several Midland and Retevis models adds to its appeal, allowing a wide range of users to benefit from this product.

There are some considerations to keep in mind. The antenna's height might be a concern for users in areas with height restrictions, as it could potentially interfere with tree branches or other obstacles. While it boasts good durability, users should still be cautious about extreme weather conditions, as extreme winds could affect its positioning. Additionally, testing the SWR (Standing Wave Ratio) requires precise calibration and may pose a challenge for some users who are unfamiliar with radio equipment.

The TWAYRDIO Heavy Duty GMRS Mobile Radio Antenna performs well in several key areas critical for GMRS antennas. With a frequency range of 462.550-467.725 MHz and a VSWR less than or equal to 1.5, it ensures efficient and reliable communication. The 6.5dB gain is substantial, enhancing signal strength for better transmission and reception over longer distances.

The antenna's length of 43.3 inches (110cm) strikes a good balance between size and performance, providing effective coverage without being overly cumbersome. The included mounting bracket with 2 U-bolts offers versatile installation options, making it suitable for various vehicles and setups. Its spring base adds flexibility, reducing the risk of damage when driving on rough terrain, which is beneficial for off-road use.

Constructed from black fiberglass, the antenna is corrosion-resistant and can withstand outdoor conditions, promising durability and consistent performance over time. However, at a weight of 3.09 pounds, it might be considered somewhat heavy, which could impact ease of installation for some users. The package includes a 16.4ft RG58 coaxial cable and necessary adapters, facilitating straightforward setup with compatible GMRS radios like Midland and Retevis models. The TWAYRDIO Heavy Duty GMRS Mobile Radio Antenna is a robust choice for users needing reliable, long-range communication, particularly in outdoor and off-road environments.
