Abstract: In an impedance conversion circuit, since, in a low band, an absolute value of impedance of a primary side coil is smaller than an absolute value of impedance of a capacitor, a high-frequency signal in a low band propagates through a transformer. Thus, impedance matching of a high-frequency signal in a low band is performed by the transformer. Since, in a high band, the absolute value of the impedance of the capacitor is smaller than the absolute value of the impedance of the primary side coil, a high-frequency signal in a high band propagates through the capacitor. Thus, impedance matching of a high-frequency signal in a high band is performed in the capacitor. Accordingly, impedance matching between a high frequency circuit and an antenna element is performed in a wide frequency band.

Abstract: The satellite dish snow shield is an add-on device that is designed to fit most commercially produced satellite dish sizes and shapes, and self-aligns as it is installed. This snow shield is a solid curved hood-shaped barrier that attaches at the top of the satellite dish and extends out at a relatively perpendicular angle from the face of the satellite dish. In this way, the snow shield prevents snow build-up and signal disruption by catching and diverting failing snow before it reaches the face of the satellite dish. This satellite snow shield does not, in any way, shroud the actual face of the satellite dish (antenna). Snow falling on these shroud type devices can themselves collect snow in a way that will eventually cause signal loss. However, no matter how much snow accumulates on the snow shield, my device continues to allow for a clear and unobstructed satellite signal to reach the dish (antenna).
