This is one kind of standard POI operating for 4in4out from 340-2700MHz, which are widely used for the DAS,Tetra solution. This box is designed specifically to support multiple frequency bands, separate link budget optimization of uplink and downlink signals, and provide independent controls for each antenna.As the manufacturer of RF passive components, our engineers can assist you to analysize the system to figure out the suitable POI according to the solution. so our engineer has the rich experience to custom design the budget POI for the system as the stable performance,the fast response will be done once confirm the defination of the parameter.
