This is a small antenna that can be made for any band similar to the AX1. Works well with Elecraft KX2 or radios with built in tuners.

To figure out band configuration. Need to determine inductance needed. I used this calculator on the web.

Once the Microhenry is know. I used kit and parts calculator to determine turns on the toroid.
I used a t50-2 but you could experiment with others.

Once I had that I added a few extra turns and used an antenna analyzer to bring the SWR down and and get as close to a 1:1 match as I could. Then the tuner would take care of the rest.
These are the parts used in the build.
