The precision interface can easily be damaged by improper disconnection or re-connection. Follow these steps if you must reconnect an antenna: 1. Inspect the antenna receptacles on the module; don't use if deformed or damaged. 2. If possible, acquire or 3D print an installation tool. If using a tool; follow the instructions found with the tool. 3. For manual installation, align the connectors so they are perpendicular. Attempting to engage connectors at an angle damages both connectors. 4. Press the antenna wire connector straight down onto the module receptacle. You should hear an audible click and mechanical snap when a proper connection is made. Note MHF4 connector is a tough nut to crack, especially for first-time users. It has to be dead-center and 90 degrees straight down to be pushed in with a tiny bit of force. Easy does it. Yes, it's a bit scary (just like first time riding a bicycle.) Do not ever think to try using a slightly tilted angle to wiggle it in. That will probably hurt the connector alignment itself.
