Antenna Tuner Design . Depending on the impedance at the antenna input (and the overall design of the tuner) you may not be able to obtain a flat 1:1 swr on all frequencies and bands. Using this atu will prolong.
Antenna Tuner V2.0 Rob's Blog from robs-blog.net
Since this tuner does all the impedance matching needed, nothing more than a simple 1:1 current balun is required and strongly recommended. This little qrp (low power) antenna tuner has been around for a while and it is sold as a kit from aliexpress, amazon, ebay, banggood to name a few. • it is used to match high impedance source to low impedance load.

Is it true that an antenna tuner does not really 'tune' the antenna? The main loop is made from ~5m of 7/8inch heliax cable and the coupling loop from soft copper tubing. The tuning capacitor is homemade and a butterfly design. Once you have modeled the antenna to determine its complex impedance, then the balun and antenna tuner can be.

Due to different antennas and operating frequencies, the impedance presented by the antennas can vary greatly. How does an antenna tuner…tune? • an antenna tuner (coupler is a more correct term) is an impedance matching device which minimizes “mismatch” loss (maximizes power transfer).

Therefore, if your antenna tuner is located where most are (in the radio room), the impedance which the antenna tuner sees is the impedance of your antenna, but it sees this impedance after it has been transformed by your coaxial cable. That’s where the antenna tuner comes to the rescue. I’m just now in the process of topping the batteries.
