Hello.   Please help. 
We have an MR200 4g on board our motorhome and sometimes have trouble with the mobile network signal strength as we go to remote places.

Im thinking of getting a couple of external antennas to help when the signal strength is bad.   
my question is are the standard factory supplied antennas on the MR200 for the WIFi frequency and/or for the 4g mobile network frequency? 
we don't need to extend the WiFi range only to try to boost the 4g signal.  
Thank you.
