Which antenna for 3g to choose?

Question

Antenna

Very weak signal (one division or not). It will be necessary to put on the second floor, there is no visibility of the tower.
What antenna to take to use in a whistle or wifi router of the provider (small)?
Active can eat? What is optimal? I want an efficient and compact option (you need to take it on trips)
Does it make sense to take a long cable? Or put on a windowsill? Or on the wall?
Or just a modem in the router and set it high?

Answer 1

In order to correctly select and configure the equipment, it is desirable to know the signal parameters in decibels.
If there is no direct line of sight of the tower, it is better to take a panel antenna, it is easier to set up and works well with the reflected signal.
