This is post 2349 in a continuing series of simple ham radio antennas.
Antenna "tuners" are a fact of life for most radio amateurs. These impedance matching transformers enable us to use compromise antennas to their fullest ability while keeping dangerous SWR levels away from out sensitive transmitting gear.
In this well-paced video, David Casler reviews the pros and cons of manually antenna tuners, discusses the theory behind these devices, and shows us how to properly operate these ATUs (antenna tuning units).
Here are some general comments from Dave:
Manual antenna tuners are less expensive than the automatic ones, and are perfectly okay for your station. This video shows how to tune a manual antenna tuner, both with an external SWR meter and with the SWR meter built into your transceiver.
Thanks for joining us today.
