Have long wondered whether I buy the antenna. In nachhinen it was a good decision. Use: Use it with the Huawei E5372 Cat4 WiFi LTE Mobile Router (150Mbps). First SIM card from an Aldi Talk. Without antenna I have at home is no reception, with the antenna fully extended 2G. Second card: SIM with LTE by T-Mobile: Without card just Emfang 2G, 4G with antenna and four bars !! Am fully satisfied. Whether it brings each time the same If you attempt I can not tell. My combination is an excellent fit. Clear recommendation.
