5. Detect the safe direction and position with the strongest signal on the top of the building or surrounding by using the mobile phone; It would be better to make it near to amplifier in order to be easily maintained; Keep the outdoor antenna away from the high frequency aerial, metal net, high voltage cable or transformer; Be aware of avoiding suffering from thunder and lightning strike.

6. Adjust the outdoor antenna, as usual, it should be fixed straightly and face the direction of the base, as illustrated in the figure1 above.
