Quarter Wave Line Matching Transformer
This page allows you to calculate the impedance required for a 1/4 wave
(electrical) section of line. To calculate the electrical length of the line
you need to multiply the velocity factor of the line (available from the
supplier of the line) by the free space length of 1/4 wave |

Tuned RLC Circuit
calculator Tuned RLC Circuit calculator, Two variables are required
(besides coil resistance) for each calculation. If two variables are set
without resistance, resistance is taken as zero. If resistance is zero, the
answers are for both series and parallel circuits. If resistance is not
zero, the answers given are for a parallel circuit |

Satellite dish alignment
calculator Azimuth is the turning of your satellite dish East and West
or Left & Right, Elevation is how high up the signal is coming from. You can
usually measure your elevation based on the degree markings on the back
bracket of your satellite dish antenna, Skew or Polarity is how much you
turn your LNBF. Standing in front of the satellite dish, looking at the
dish, if you have a positive Skew angle you want to turn your LNBF
counter-clockwise |
