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.
withstand the transmit power of 15W,the tuning range of approximately 40-300 ohms, can be very convenient for QRP communication, to ensure high efficiency radio transceiver in communication, but also allows you to fully enjoy the fun of DIY.
BUILD AN HF ANTENNA TUNER MAKE A HOMEBREW HF-VHF ANTENNA TUNER (It really isn't all that difficult.) This page details several T-match tuners. By comparing them, you should be able to construct a tuner to your own particular requirements.
Using some old components left over from prior projects, Jim W6LG builds a manual antenna.The Patreon Link: patreon.com/JimW6LG.
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
The QRP Manual Tuner appears to be the combination a few pieces of work, some that are possible to locate on the Internet. SWR Indicator Circuit - Dan Tayloe N7VE LED SWR indicator
Basic multi-z antenna tuner for QRP. Easy to tune low-z and high-z antennas. This is just an experiment while testing it with my 40m EFHW antenna.
