What is ganged tuning capacitor?
The ganged capacitor shown here is a combination of two capacitors connected together. A single shaft is used to rotate the variable ends of these capacitors which are combined as one. The dotted line indicates that they are connected internally.
What is butterfly capacitor?
A butterfly capacitor is a form of rotary variable capacitor with two independent sets of stator plates opposing each other, and a butterfly-shaped rotor arranged so that turning the rotor will vary the capacitances between the rotor and either stator equally.
What is the use of tuning capacitor?
Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.
Do magnetic loop antennas work?
Magnetic loop antennas are your friend. By design, mag loop antennas are some of the best antennas for mitigating the radio frequency interference (RFI) that plagues so many of our homes and neighborhoods. When oriented vertically, mag loop antennas can also be rotated to null out unwanted signals on lower frequencies.
Does a magnetic loop need a balun?
If signals came only from the loop, then sure, there would be no need for a balun. But the feedline is also effectively a big vertical antenna in the common-mode, and is going to pick up signals as such.
Are magnetic loop antennas any good?
What is a trimmer capacitor?
A trimmer capacitor is a variable capacitor used for initial calibration and recalibration of equipment. It is commonly mounted directly on a PCB and accessed only by professional repairmen, not the end-user.
Where can I buy MLCC capacitors?
MLCCs (Multilayer Ceramic Capacitors) are available at Mouser Electronics from industry leading manufacturers. Mouser is an authorized distributor for many MLCC capacitor manufacturers including ATC, AVX, KEMET, Murata, TDK, Vishay & many more.
