Wireless Joint

I had to replace the M1 MHF4 connector on em20-g PCB because it was damaged. After I got it from the repair shop, I tested for continuity on M1 between the inner pin and outer ring and there was current flowing. I used ohmmeter set to 200. Should there be current between the two, or did the tech create a short when he soldered the new connector? If someone has this modem, can you please test it and let me know? Weird thing is I tested M2 and it also had the current flowing like M1, and M2 wasn't replaced.
I'm freaking out now.

It's normal to have conductivity between the middle and ground, since it's bridged with a filter. Unlike AC/DC, radio waves travel through this circuit just fine. That soldering job looks pretty rough/amateurish, but it doesn't look like it's shorted out. Just test the download speed which should tell you if there's a problem.
