An Automatic Antenna Tuner (AAT) is a device that adjusts the impedance of an antenna to match the transceiver, thereby optimizing the performance of radio transmission and reception. These tuners ...

To get the best power transfer into an antenna, tuning is required. This process uses a load to match the transmission line to the antenna, which controls the standing wave ratio (SWR). [k3ng] built ...

[Tech Minds] built one of those cheap automatic antenna tuners you see everywhere — this one scaled up to 350 watt capability. The kit is mostly built, but you do have to add the connectors and a few ...
