So I splurged on the Alientech Duo II for my Smart Controller due to Alientech telling me this will help me in the mountains where I live. I have the Mini 2 and the Zoom. After installing successfully, my test flights with the Mini 2 showed absolutely no difference. In fact, the signal drops very fast and I am completely losing connection to the point of the drone returning to home. That never happened with the stock antenna. Anyhow, if anyone has any ideas to improve signal, I'd love to explore all options. I'm not giving up on the Duo II just yet. I contacted support in hopes I am doing something wrong.
