Hello Alberto and Daniele and VLF,

Yes, this is what Chris/4X1RF observed as well. It can make a very significant difference just to lift the antenna by 2m higher above the previous location!

Additionally, I didn't perform specific tests with the E-probes, like for example attaching them to a fishing 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.
