If it is possible to get the antenna checked that may be the way to go.
I think you can connect the aerial using the NMEA cable directly to the GPS. This is the only device that you can do this with. The idea being for people who do not want to set up an NMEA network you can still use a lowrance head unit with a GPS aerial.
No harm in trying!
As for it dropping off the network. Even if you think all your connections are good I did find that I had an issue on mine where the fuel guage sender kept giving an intermittent reading. In the end I worked out one of the T pieces was causing issues.
it worth swapping things over, for instance connect one of the LMF gauges to the T that your GPS antenna is using to see if the problem follows the T piece.
