This is post 2568 in a continuing series of simple ham radio antennas.

An antenna transmatch (i.e. tuner or coupler) is a familiar piece of equipment in many ham shacks.  "Tuners" insure that impedances between antennas and transceivers are matched to allow maximum efficiency.

In this video, Michael Martens (KB9VBR) shows us how to properly use an antenna "tuner" to maximize your antenna system.  Michael uses the popular MFJ-949E (I use the same tuner) to demonstrate basic "tuner" concepts.

Here are some of Michaels comments:

Antenna tuners are a vital, yet slightly misunderstood ham radio station accessory. In this video we talk about what an antenna tuner does and doesn't do, how it works, and how to tune your antenna system with a manual antenna tuner.

Amateur radio transceivers expect a 50 ohm impedance from the antenna, but not all antennas will deliver that impedance. That’s where the tuner comes in. A tuner typically consists of an inductor and variable capacitors can be adjusted to create the proper impedance. Now tuners don’t actually ‘tune’ your antenna. They don’t change the physical characteristics or make the antenna better. Instead they just provide the proper impedance match to the transceiver, so the transceiver can operate in a more efficient manner. #AntennaTuner #HamRadioHowTo #HFradio
