As mentioned, they don't go well with the Nighthawk M1 AP. Landing is free and external antennas will "hang out". There should be a stronger connection. When comparing the signal values, they were no better than when using an access point without an antenna. In fact, downloads without an antenna were faster than with external antennas. There may be a loose contact. Antennas may be present. However, I tested 3 different antennas. The other two had TS9 connectors that fitted just right.
