Do you happen to know the version?

I believe it's a E160, but no one confirmed that so far. You could revive the following thread, which I had opened for that purpose Bitte an Besitzer folgender Sticks: O2, Fonic, Vodafone K3565, MedionMobile S4011 - Telefon-Treff, maybe some owner of the Aldi stick will reply.

Are there major differences between the different letters versions?

The differences are the supported 3G frequency bands, as you can see at Huawei E160 (E160G, E160E, E160X, K3565) - 3G modem wiki

Did you ever try if an external antenna e.g. 10 dBi improves the reception, of if the transmission line loss in the cheap thin cable compensate the antenna gain to 0

No, I have no experience with antennas on 3G devices, but a good source for cheap antennas of high quality is UMTS-, WLAN- und DECT-Informationen, Tipps und Tricks sowie Web-Shop. They use high quality cable and when ordering you can chose the connector type and cable length of your antenna so you can reduce signal attenuation by a short one. I've bought WiFi antennas from them before.
