    View details. Practical construction details are described in the next paragraph. Magnetic Loop Antenna for Meters. In AM radios built prior to the invention of ferrite in the midth century, the antenna might consist of dozens of turns of wire mounted on the back wall of the radio — a planar helical antenna — or a separate, rotatable, furniture-sized rack looped with wire — a frame antenna. Additional gain and a uni-directional radiation pattern is usually obtained with an array of such elements either as a driven endfire array or in a Yagi configuration with all but one loop being parasitic elements.

    The monograph, "Magnetic Loop Antenna, A Bit Different Every Time", is an unique study that in technical literature has no similar works to compare.For a given loop area, the length of the conductor and thus its net loss resistance is minimized if the perimeter is circular, making a circle the optimal shape for small loops.

    A loop antenna is a radio antenna consisting of a loop or coil of wire, loop antennas, commonly called "magnetic loops" or "mag loops,".Why do you build your loops as squares instead of circles or octagons?

    Product Overview. Magnetic Loop Antenna's Book 4th Edition, Radio-amateur traffic on short-wave bands using MLAs during a few last years has increased. · Reviews.Remember that even with only a few watts of power, there can be thousands of volts across the capacitor and several amps of current through the capacitor not necessarily in phase, no free power!

    Magnetic Loop operation is mysterious and seems to be almost magical. To gain knowledge and understanding of these remarkable antennas, the book.Small transmitting loop antennas are very useful when space for a full size antenna is limited.

    The ARRL Antenna Handbook's equations helped me put a little design effort into these antennas so that I could make them work the way I wanted them to work.The UHF loop described later this page is very small and was made as efficient as possible without resorting to silver plating or superconducting construction yet it still gets very hot with only 10 watts of RF at MHz.

    The small loop antenna is also known as a magnetic loop since the response of an electrically small receiving loop is proportional to the rate of change of.Losses in conventional capacitors can be high due to the several milliohms of resistance found in their brush contacts and non-welded vanes.

    In order to couple to a transmitter or receiver, the inductive reactance is normally canceled with a parallel capacitance.

    However, unlike with capacitors, the voltage change is gradual, spread across a physically long inductor, and is generally not troublesome.

    The radiation resistance of the antenna is very low and therefore it's very important to keep the DC losses in the range of milli-Ohms.

    Most loop literature would say that the wiper connections on commonly found air variables are too lossy.

    Loops can be placed on rotors and the loop can be turned for best signal strength or it can be used to null out offensive interference.

    The radiation resistance R R of a small loop is generally much smaller than the loss resistance R L due to the conductors composing the loop, leading to a poor antenna efficiency.
