A lot of customers get confused with the terminology cell phone repeaters and cell phone amplifier. The main difference is that one is a complete system with a receiver antenna and donor antenna both receiving and broadcasting cell phone signal. The other only amplifies the cell phone signal and requires antennas to complete a full system . In other words if one is looking to boost cell phone signal for their home or vehicle , they must get a complete system which include a receiver antenna and donor antenna . One antenna must be mounted outside the home or vehicle and the other antenna must be mounted inside the home or car. Their are several options for picking the external (donor antenna) and internal (receiver antenna) . For the external donor antenna ,you can choose between a direction sensitive YAGI antenna or omni directional antenna. The Yagi antenna is most suite for situations were the signal strength is very poor and the yagi does the job of getting the most signal from a given location. The reason the Yagi is so effective in week signal situations is because of its ingenious design and signal attraction properties. The yagi frequency is determined by the number of elements in the design and that along with the spacing between each element determines the effectiveness of the antenna and the specific operation.
