For the transformer I plan to recycle the one osed for the loop. It has two big toroids 80mm external diameter

and 8mm thick. Both joined make 16mm thick. Unfortunately don't know which is the material used

Can be primary and secondary be wounded one on top of the other ??

Tonight reports on my remote monitor are 3dB down. I made a modification

I have finally connected a wire from top terrace to the fire extinguish pipe which runs inside the building down

to the basements, were pumping system is located. The wire is not yet connected to the ground side of the vertical

BUT the actual radial counterpoise runs parallel to this wire for about 5m

Seems like this can be the cause of 3dB looses.

 Keep tuned !
