Unfortunately these items don't work for me. I entered the Huawei modem settings and changed the antenna settings. The signal actually went down when set to two external antennas. They are white and look impressive, and look as if they are there to do a good job. They look identical but perhaps not. If I feel like it I might swap them over, but I don't have any hope of improvement. If there is I will update this comment. 5 Stars for delivery though. Ordered at about 10am and delivered at about 2pm next day. Phew!
