I would say that if the connection fits, then the antennas work with all modems. As far as I can tell from the picture, the connections are under Y1 and Y2. These are the sockets that the Netgear antenna has.
This is buest guess - no guarantee.
Thank you very much for answering my question. The Huawei box has 2 Ts9 antenna connections. I just wasn't sure if the Netgear antenna would only fit with the Netgear modem. I will try it that way. Thanks again and best regards
