It slides neatly into the base of the antenna tube.  I've added
a calibration port which works great.

My new calibrator, built into a plastic toolbox,

has outputs for voltage injection into the E-field front-end
and current injection to the H-field.  Looking forward to
running it in anger up at the antenna site.
That's always interesting to see. The shack and homemade stuff tells a
