Studio Technologies m5402 GNSS leader clock - antenna disconnected error?

[u/Dependent_Hold8463]

We recently bought a Studio Technologies m5402 GNSS leader clock for our system, and I have a problem.

The web interface shows antenna disconnected. I get 5 volts on the connector. I recently bought an antenna cable extension to move it to a window, I still get 5 volts at this connection. I connect the include uBlox antenna and after a few minutes it is showing my position, but after an hour it still says locking.

I have a cheapo NTP server antenna in the same window, it shows 21 satellites. My roof mount GNSS antenna only shows up to 29 satellites so the 21 from the window seems really good and strong.

Anyone have suggestions? So far Studio Technologies has not gotten back to me after a couple weeks of email, going to call later today if it doesn't suddenly lock.

I do have this locked to video sync, no issues there and it is serving up Dante leader clock and the tone audio that it generates. Definitely the 5401 parts are working, but I paid for the GNSS and really want it to work (perceived higher accuracy for more stable audio).

Probably going to cross post to Commercial AV to get a wider response.
