This circuit diagram shows the interconnections of parts for a very basic preselector which goes between and antenna and a radio. Source Drawn using free software by me using a well known circuit Date 2014-10-29 Author JNRSTANLEY. Permission (Reusing this file) See below.
English: The image gives six circuit diagrams (schematics) for balanced line antenna tuners of the tuned-transformer type, discussed in the Wikipedia article "Antenna Tuner" or "ATU". It is an edited version of the original by JNRSTANLEY uploaded 2014-10-15.
A signal transmitted over a balanced line. The signal is kept intact while the noise (which appears as a common-mode signal at the receiving end) is rejected perfectly.. In telecommunications and professional audio, a balanced line or balanced signal pair is an electrical circuit consisting of two conductors of the same type, both of which have equal impedances along their lengths, to ground ...
A phase equalizer is a circuit which is cascaded with a network in order to make the overall phase response more linear (or to make the group delay more constant). The combined circuit will transmit waveforms with improved fidelity, compared to the performance of the initial network alone.
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
AN-SOF - A Windows simulation software for antennas in free space and above a lossy ground, microstrip patch antennas and printed circuit boards (PCBs). A radial wire ground screen is included and connections to imperfect ground are allowed. Not based on NEC. AutoEZ - An Excel application that works in conjunction with EZNEC v.5.0 & v.6.0 ...
The rhombic antenna is a directional wire antenna used on MF and HF bands for shortwave reception. The antenna consists of a wire suspended above the ground in the shape of a rhombus , terminated at one end by a resistor equal the the wire's characteristic impedance, about 400 to 600 ohms, and at the other end connected to the feedline to the ...
The polar diagrams (and therefore the efficiency and gain) of Yagi antennas are tighter if the antenna is tuned for a narrower frequency range, e.g. the grouped antenna compared to the wideband. Similarly, the polar plots of horizontally polarized yagis are tighter than for those vertically polarized.
