Just be sure that you situate the 'remote' antenna where it CANNOT hear the repeater antenna, or it may oscillate (feedback) and get you into heaps of trouble with the Telco (an oscillating repeater can jam a cell site). I learned of this problem from a telco tech whose job requires he locate such 'interfering' repeaters. He had some interesting stories about how many ways people can screw up the installation. In the USA you can be severely fined for "interfering with a telecommunication service" if you screw up the install.
