Question about GNS Electronics GNS 3000

Hello,
the device has no noticeable improvement in reception compared to conventional mobiles. Even if you stick it to the window.

In railway vehicles, wagon crossings are generally better illuminated by GNSS satellites. However, there are trains that are either very old and transparent to signals, or are equipped with modern radio signal-transparent windows. The enemies, however, are the trains whose window panes attenuate EM waves of all frequencies. The ICE 1/2 and ICE 4 are particularly bad (according to DB, this will be improved at some point).

The rule is: if it doesn't work on the window panes, go to the coach gangway!

VG.

I can't judge, I haven't used it on the railway
