Antenna Issues On La400
My antenna seems to have issues. I could previously be 70-80 ft away and remotely open the gate. Now I need to be 5-6 ft away and have direct line of sight to the control box. I tried tightening the coax connector. It's secure and not corroded. Do I need to replace the entire motherboard or is there another option? I've had this for 8-10yrs

I fixed my issue. I replaced the top antenna with a $10 aftermarket replacement one from amazon. Works great. I probably should have removed, sanded, and reseated it before replacing...but the new one works fine. I'm guessing it was a loose connection on top.
