Hi Stefan,

+6 dB, so now you're getting twice the antenna current with
the same power?

No,only about 10% more (calculated) as the VSWR is a bit better.
R went from ~60 Ohm to 50 Ohm,reactance being cancelled out.
The increase in signal strength by 6dB comes from reduced ground losses due
to vertical polarization as opposed to horizontal polarization in dipole mode.

Can you show us the image showing your house and the antenna again? I

Attached once more for convenience (see also link at the end).
Red traces = dipole legs (2x155m)
Yellow trace = open wire feeder (42m)

remember there was a coax of some 10m between TX and dipole feed point

That must be someone different. -:)
Here the feeder runs directly into the shack,vertical part about 6m.
So in T-Antenna mode there's quite a bit of top load...

Let's see how I can manage the earth problem.
I believe for reception I will further stay with the dipole mode because it's 
extremely
quiet ( -110dBm or true ~S3 in 200Hz BW) due to careful balancing and its remote
location from the houses.
When receiving I can afford up to 10-15dB signal loss on MW without
degrading SNR.
