WebJust look at the power handling at 60 ohms - below 50%. It is horrible! At the compromise value of 50 ohms, the power has improved a little. So 50 ohm cables are intended to be used to carry power and voltage, like the output of a transmitter. If you have a small signal, like video, or receive antenna signals, the graph above shows that the ... WebDec 25, 2024 · The 60MHz 250Msa one should technically be better according to the spec, but it looks so much more cheaply made than the 20Mhz alternative. The 20Mhz also goes for a higher price when new. Is there some features the cheap 60Mhz one is missing? such as adjusting output impedance. Or should I trust it? Many thanks! Logged ledtester Super …

WebExample calculations: Absolute vs per unit Consider a 1000 kVA, 5.75%Z, 12.47 kV to 480Y/277 transformer. The constant of proportionality used to convert per unit impedance to absolute impedance is the base impedance. Equation 8: Z ohms = Z pu *Z base Beginning with the 480V secondary, the base impedance is calcu-lated as: Equation 9: Z base ...

For the case of resistive loads (see sidebar), the SWR can be easily calculated as equal to the (Load R)/Z0 or Z0/(Load R), whichever gives a result greater than or equal to 1.0.
