Additionally, I didn't perform specific tests

rod (or other support)
to put them well outside of my balcony at 5th floor, that
probably would have given a substantial improvement.
I can confirm from my direct experience that an E-probe must
be placed up in the air, free from obstacles.
When I built for the first time the Roelof's mini-whip I tested it
on the balcony of my house, on the second
floor of a two-story single house. It performed so badly that I
thought to have wasted my time and my money.
Then, remembering a few suggestions read on Internet, I moved it to
the highest point of the highest chimney
of the house, far from obstacles, with a free 360 degrees range, on
top of a 2-meter pole.
It resurrected to a new life ! This is how the Russian Alpha
stations are received from my mini-whip on the roof :
So my suggestion is to place an E-probe antenna as high as possible,
free from nearby obstacles.
