Welcome to www.lxqqfy.com to get the latest information. The kit can be through the T network resonant antenna, to make the radio work normally. Change SWR, corrections due to external reasons not tuned antenna. Can be used as a bandpass filter, Reduce the harmonic in the transmitter, to reduce out of band cross modulation and interference when ...
My homebrew antenna tuner is capable of handling 100 watts if I need to use it with my IC-7200 XCVR. I will publish the results of my experimental tuner on this page as I progress through variations of it.
Shorter-than-full-sized antennas (e.g. loaded whips, dipoles, small loops) will have whackier impedances and much much narrower matching frequencies. Antenna tuner almost always needed for those….

18 kwi 2020 · Antenna tuners (more accurately referred to as “transmatches”) make great homebrew projects; they are reasonably simple to build and, when finished, provide a useful piece of equipment. Every shack should have (at least) one.
It’s an ATU, antenna tuning unit, aka coupler, matchbox, or whatever your preferred term is for an impedance matching unit. It was given to me by Graham, VK2DIG, on the condition that I work out how it works. This article describes my findings. First impressions… it’s homebrew, made evident by hand written labels on the front panel, but well
