An advanced engineering approach to tuner development has resulted in truly highest quality hardware and software solutions.

Our software developers have extended the tuner with new functions, and completed integration with Antenna Genius, forming a single system. Very easy to use, uncompromisingly functional, the integration of TGXL into the Genius platform extends both functions as well as protection systems.

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.
TGXL also features an extremely accurate power and SWR meter.
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. 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.

A careful calculation on all frequencies and impedances has enabled us to to choose the best components and making the tuner as efficient as possible. It also features mechanisms for protection in extreme cases by reducing the maximum working conditions and protecting RF components from damage.
