Hello Everyone, 
 
	I was wondering if you could give me some advice on how to modify the following device. It is a Dahua Doorbell DB10. The range of this doorbell is very limited, which creates a lot of latency problems due to the weak wifi connection. 
 
	Perhaps it would have been better to get an antenna extension for the WIFI router, but since I cannot drill the wall to place the antenna facing outside, this was my last option. My idea is to get a cable to solder to the places the antenna was soldered and then connect it to the antenna of a broke router or perhaps build a directional antenna.
 
	If you could be so gentle to inform me, what materials should I use to connect the device with the new antenna:
 
	- Cable RG? LMR? what type?
 
	Any type of information will be much apreciated.  
	 
 
	
 
	I should weld a piece of the cable from one side to the other, and then from that same side to the antenna, correct?
 
	 
 
	 
 
	Here i took apart the antenna that was inside the device.
