Working on the vacation

I've just bought a 4g antenna that I'm going to use when I'm on vacation. It's not actually a real vacation since I have to work from there. But I wont work all the time so I will still have some time to do other stuff. But with this antenna I can get a stronger signal even if the internet signal is really weak. So that's really good. I'm not sure I will need it, but I just want to be sure that I can get a internet connection from over there.
