The main loop forms an inductor and to tune the loop, a variable capacitor is connected across the inductive loop. At the desired operating frequency, the system is resonant with an operating bandwidth of only a few tens of kilohertz.

Loop Tuner. Turn wire or coax into a small, high-efficiency multi-band transmitting magnetic loop antenna! Work the world from 3.5 to 30 MHz using a full 150 Watts on sideband, CW, and digital. Â

In order to achieve good matching to the transceiver, and high efficiency, a small loop needs to be tuned by a capacitor between its ends. High currents flow in the loop, hence it needs to have very low resistance.

With MFJ 932 high-efficiency Mini Loop Tuners™, you'll radiate a low-angle DX signal that literally rivals full size dipoles! They also function as very quiet receiving antennas, and since they respond to magnetic fields and not electric fields, you'll hardly notice static crashes during a …

The AlexLoop portable HF loop antenna provides radio enthusiasts a fast, effective and affordable way to enjoy operations on-the-go.

Ideal tuner for experiments with magnetic loop antennas. Simply wind a wire around a frame or hang it between two trees and connect both ends to the MFJ-935C antenna tuner - and you have an efficient Magnetic Loop! The MFJ-935C uses a large butterfly capacitor to …

This tuner is designed for remote automatic tuning of the F-LOOP 2.0/3.0 magnetic loop antennas in place of the standard manual tuning knob. This permits the antenna to be up to 12 feet from the operating position, such as on a balcony or deck, and enables precise automatic tuning of …
