The Ground Plane Antenna designed for the 118–135 MHz airband is a robust, omnidirectional antenna engineered for reliable VHF aviation communications. With 0 dB gain, it provides a true, uniform radiation pattern that ensures stable signal performance in all directions, making it ideal for both transmit and receive applications where consistent coverage is required rather than signal focusing.
This antenna operates efficiently across the entire civil aviation VHF band, supporting applications such as air traffic control (ATC) monitoring, airport ground operations, aviation receivers, flight schools, and aircraft communication base stations. The ground-plane design uses multiple radial elements to form an effective RF reference, resulting in excellent impedance matching, low VSWR, and clean signal characteristics.
Constructed from high-quality corrosion-resistant materials, the antenna is suitable for long-term outdoor installation. It performs reliably under harsh weather conditions including high temperatures, humidity, wind, and rain. The vertical polarization matches standard aviation communication systems, ensuring compatibility with airband radios and scanners.
The 0 dB gain characteristic preserves the natural signal strength without distortion, making it especially suitable for short- to medium-range airband coverage where clarity and accuracy are critical. The antenna can be easily mounted on masts, towers, or rooftops and is compatible with commonly used VHF coaxial cables and connectors.
