Attached to my wall, I have a 6 foot long metal tube. With the addition of some form of connector it too, like your Eurostick, will receive signals between 25 & 2000 Mhz.
On top of that pole I have my three band colinear. This was designed to work on three bands. It may not be any better than the pole supporting it on many frequencies between 25 - 2000 Mhz, but it was designed to work on known frequencies.
My concern with any receive only antenna is that any lump of metal will receive on all frequencies to some extent or another, but it does not mean that they are designed to work, not even work badly, within it's specified band coverage. Just that like any lump of metal they will work to some extent with that specified spectrum perimeter.
Your Eurostick will work between 0.5 mhz & 10,000 mhz or even 0.1 - 20,0000 Mhz to some extent. But I would not reccomend it at Medium Wave or Wi-Fi frequencies any more than I would recommend it at Air or Marine band frequencies.
