Initially, I had significant fluctuations in the LTE bandwidth of at least 3-27 Mbps. The assumption was: It is up to the different traffic for the other users. When I then carried around the Vodafone modem just once in the room (original Lan cable has been replaced) I found an approximately 10 square centimeter large place to which the modem had the best reception of 27 Mbps. The catch: The site was impossible to permanently position the device there in the middle of the "air". So I bought this outdoor antenna plus Twin cable. The assembly is carried out on a balcony railing and was very simple. For this everything is included. The alignment in the direction of the signpost was also no problem. To this end, the antenna offers several options. A window procedure was not necessary. I put the cable in the Fensterramen. Goes without problems, since the twin cable is relatively flat. Now have a stable range of 25-28 Mbps (21 Mbps Contractually agreed). Tip: You should inform about the position of the transmitter mast is essential. Buy recommendation.
