Antennas Tuners do not Dissipate Heat (

Timothy, W6WWW, has his transmitter consuming more power from his power supply than it should. Watch to learn more ways to control the power reflected from the load.

Excellent class.

Thanks for answering my question Dave! 73 de W6WWW!

[@billmcilwee566]

Very well explained! Thank you and 73, KF0NNQ.

how will reflected power from ant tuner back to antenna affect the total radiation power from antenna given it's phase delayed?

[@timdbl7804]

0:11 I think tuners, at least in amateur radio world, have typically 1 dB loss, sometimes I have heard as much as 3dB loss on the lower bands, e.g. 1.8 MHz. Running 1 kW with a tuner of 3 dB loss will soon get pretty warm! All real-life capacitors, and especially inductors, have some loss. However, I would agree that in a lot of cases, e.g. 100 Watts and well designed and built tuner, the heat dissipation will not be a problem.

How much heatses does its nots disapateses precious

Thank you. Have a great week. N0QFT

Your explanations are like trying to bring calculus down so a second grader (me) can understand it. I wonder, are you an Electronics Engineer?

[@BusDriverRFI]

If your antenna is perfect, it will have an inductive reactance equal to the capacitive reactance. The reactances will not be zero. They will add up to zero.

Real world capacitors and inductors have a non-zero R component, they are not R0 +/- jx, this will produce heat and that thermal energy must go somewhere.
