Mag-mount 136kHz E-field probe picture

This is a photo of the E-field probe used some years ago to receive my very low ERP 136kHz QRSS3 signal on the far side of Cambridge (20km?).  It was mounted in the middle of the car roof.  As you see, the whip was very small!

UPDATE 1550z: Well, I found the EFP in a drawer, but the coil and cap in the drain had been removed years ago. If I want to resurrect this, I shall have to rebuild this part. A nice small project over the spring or summer.
