NOTICE: In July 2021 the channel name changed from HamCuredSmoke
To Ham Radio A2Z. All of the earlier videos (like this one) are still available.


In this video we will look at how to graph the SWR of your antenna over a range of frequencies. This handy, builtin function is a great way to see how broad your antenna is and how the SWR looks across an entire band or segment of a band that you're interested in. This function works with or without an antenna tuner in the circuit. So you can see how well your antenna is tuned or you can see what kind of tuning range a nonresonant antenna has when using a tuner.
