"My laser antenna won't even connect to over 50 meters. (creative world, build lots of batteries, just to test the antenna).. as soon as I reach 50m (500watts) it disconnects. But it keeps reporting the wattage that is corresponding to the distance, also the antenna turns the right way. but no connection."

I am experiencing the exact same issue.
Ive been trying everything yet the laser antennas wont connect. Diff grids, LOS, visual range, close, far, mods, no mods, etc. I'm struggling to understand why. Both grids have excess of 1GW power at their disposal. Clear LOS.
Discord image links because I sent this in the discord help-se ; but need to repost it here.
This clearly shows they have LOS and visual range, yet no luck.
