The MFJ cobweb antennas are a popular choice among amateur radio operators. These antennas are designed for directional communication, allowing users to focus their signal in a specific direction. The Yagi design consists of a driven element, along with one or more parasitic elements. The driven element is connected to the radio transmitter or receiver, while the parasitic elements enhance the antenna's performance by reflecting and directing the signal. The MFJ antennas come in various sizes and configurations, allowing users to choose the best option.
