Following there is the working principle of OSG-20NK grid antenna and the full kit of Lintratek cell phone signal booster:

The feed for grid antenna has high gain, so it is widely used in countryside, mountain areas where is with weak signal and far from the base station.
Because the main lobe angle of receiving is narrow, so it can receive signal far away.

1. Can a grid antenna receive signals from 10 kilometers away?
Yes, it can. Because the main lobe angle of this antenna is narrow, so the gain is high and it can receive signal far away. The most important thing is that you need to install it and make it face exactly to the signal source.

2. What is difference between grid antenna and plate antenna?
The main lobe angle of the grid antenna pattern is small. The gain is higher and is mostly used for point-to-point transmission. The flat plate antenna has a larger main lobe angle. Mostly used for coverage.

3. Can I use a grid antenna for both receiving and sending?
Because the main lobe angle is small, so it is normally used for receiving signal, for sending is not suggested.

4. How to install the grid antenna?
The grid antenna is installed horizontally, and the angle needs to be adjusted to align the signal source.

5. What is the highest gain you can make?
The highest gain we can make is 20dbi.
