If building is made of concrete steel steel roof copper roof brick aluminum siding concrete roofing tiles metal roofing tiles or any other signal stopping material a repeater is usually the ideal solution for your situation Donor antenna Wide Band Repeater Model PORP20 Most homes or buildings are easily covered by one repeater systems Some buildings are larger or have multiple areas inside that need coverage lt Donor Antenna Ai Coupler Service Antenna 1 B I 1 a I Repeater Splitter lt may need longer cables more than 2 coverage antennas or other items in order to fully cover your building We can make almost any cable length and can help design a system that fits your application 5 3 Isolation and Separation lsolation refers to the proper distance or separation needed to keep the Donor antenna signal pattern and the Coverage antenna signal pattern away from each other Repeater Cable Tx Isolation becomes particularly problematic when Omni directional antennas are used for both the Donor and the Coverage antennas Since these antennas transmit in a circle or more accurately a sphere it is very easy for these spheres to overlap and thus negate the repeater system Wide Band Repeater Model PORP20 6 Production Operation 6 1 Notices Follow below safety items carefully before installation implementation maintenance and operation for this prod
