  • Impedance matching - Wikipedia

    Whenever a source of power with a fixed output impedance such as an electric signal source, a radio transmitter or a mechanical sound (e.g., a loudspeaker) operates into a load, the maximum possible power is delivered to the load when the impedance of the load (load impedance or input impedance) is equal to the complex conjugate of the impedance of the source (that is, its internal impedance

    6. Install a ventilation fan with your audio/video equipment. Fans provide great ventilation for your A/V equipment. Fans move lots of air and when it comes to keeping your equipment cool, more air equals better ventilation. This actively cools your electronics, whereas the other techniques I discussed passively cool your electronics.

  • Standing wave ratio - Wikipedia

    The most common case for measuring and examining SWR is when installing and tuning transmitting antennas.When a transmitter is connected to an antenna by a feed line, the driving point impedance of the antenna must match the characteristic impedance of the feed line in order for the transmitter to see the impedance it was designed for (the impedance of the feed line, usually 50 or 75 ohms).
