With a better incoming signal, cell phones require less output power to send and receive a signal. This can significantly reduce the required transmission power of mobile phones and therefore reduce the level of electromagnetic radiation exposure to the human body. At the same time, having a better signal reduces power usage, which saves your battery and can and improve battery life of phones on standby mode by up to an additional 2 hours.
Restrictions about Trees: If there are tall trees within 100 feet of the house. At the same time you can't find a stable signal above 3 bars, the outdoor antenna needs to be erected 60% (at least) to 80% (best) of the tree height. Never exceed the trees.
