First, tell us what frequency you want.

I'll assume you want it at 27.165:

There is more inductive reactance than you need. Mess with the trombone a bit (make it smaller).

The resonant element is too short, make it longer.

Also, you should be using a phase matched section of feedline for this measurement (electrical 1/2 wave).

If you could put a marker at the freq. your after, that would help know what your trying to do.

It would be interesting (for me anyway) to see the Smith plot.

Have you figured out the resolution of this measuring device?
