LL-tuners & meters
PA0LL, Kees, made a S-match tuner for me some years ago. This summer he changed it into a "LL-single-L" tuner as he called it. Giving me a wider range of impedances. An unbalanced antenna connector was later added as well.
Very good pictures of Kees his tuners can be found on his site
Today he builds an even nicer tuner, his so called Hex-tuner. I had the opportunity to use one of those a few weeks ago. A very nice experiënce.
A rough schematic has been added to the Gallery above right.

A very good performing tuner. All handcrafted by Kees/PA0LL
Antenna current indicator
The antenna current indicator is a useful instrument to check the antenna current in both feeders (when using symmetrical line feeders) of your antenna. Also it's possible to see wether the current in both feeders is equal. Two sets of led-lights for each line.
