$GTCH on alert, the company is now evaluating and testing self-tuned antenna technology in order to enhance its Infinia Long Range radio performance. An automatic antenna tuning system a technology that improves power transfer between the transmitter and antenna to adapt to ionospheric propagation conditions, ensuring the optimal communication performance. High-frequency (HF) radio, also known as shortwave radio, enables worldwide coverage due to electromagnetic wave refraction in the ionosphere, this phenomenon is also known as skywave propagation.
