ATU-100¶

The ATU-100 is a fantastic little antenna tuner.
I think I’m using a generic clone (Amazon, https://amzn.to/3qCdPIg) of the N7DDC design.
It’s been great when paired with my Moonraker MU-9 9:1 UNUN, especially given the multi-band nature. My previous tuner was manual, which meant much more fiddling when switching bands!
It requires a minimum of 5W to start tuning, which was a bit of a bump from my until-then-usual 2W(!), but probably a valuable step up given my antenna compromises!
