1- Is there a way to lock the module on 2G? No it will lock onto the network of the sim card. If 3G is weak it should fallback to 2G



2- My antenna is very closed to the roof. So adding the adm02 modules should not help me I guess. Would it be possible to expand the antenna cable and put it outside on the roof? Or would an external and amplified antenna would be a solution?Ant recommended product?Thank you for your

ADM02 can still help by allowing the UCM/GSM4 module to be located in a better position

There are some who have just extended the antenna cable by cutting and joining the cablee, buy I am not sure how well that would work in general

We have another antenna which is a higher gain type see attached image
in our testing it has increased the level by 1.
