The Rigexpert magnetic loop is a tuned loop antenna and consists of a band of Copper 28mm tube circumference 6 meters (acting as a radiating inductor 2 meters diameter) with a stepping-motor-driven tuning capacitor mounted in series with the band. The LC combination is made to resonate at the chosen operating frequency. The loop has very high Q and the bandwidth narrow, resulting in attenuation of any harmonics from the user's transmitter, or strong local signals from any adjacent transmitter.
Tuning is accomplished by controlling the stepping motor from manual control based on Arduino chip. For best radiation symmetry and best SWR we will use coupling loop. 6.97Mhz-14.500 no gaps.SWR after tuning 1.2 or better. Capacitor enclosure adaptable waterproof IP56.
