Incredible Breakthrough! Infinite Variable Velocity Factor means NO TUNING any more. SWR will be a thing of the past! The VF follows the wavelength in a linear fashion. Quite remarkable! What do you think?
This short video explains what a dummy load is, and what we use them for. Callum.
This video explains SWR, how to calculate it – and should we worry about it?
