Preliminary specification of TGXL automatic antenna tuner - 2000W. The table shows maximum power per band that the tuner can handle, for different SWR values on the antenna. It also features mechanisms for protection in extreme cases by reducing the maximum working conditions and protecting RF components from damage. On the images below you can see the C block of the tuner, with capacitors that would individually endure RF currents of 10-15A and voltages from 1500 to 3500V.Ī careful calculation on all frequencies and impedances has enabled us to to choose the best components and making the tuner as efficient as possible. The RF block was carefully designed and is built from only the highest quality RF capacitors, making sure it’s capable of enduring currents and voltages generated by high SWR’s. TGXL also features an extremely accurate power and SWR meter. Once setup, TGXL will remember individual settings for each frequency change and will go to bypass if your antenna is in a segment with good SWR.
