2045466 9014720 PCTABS00002 A signal routing system for use in cellular RF communications systems wherein a signal can be routed to different antennas, effectively switching transmitters between antennas. The switching is accomplished by placing a frequency responsive device (7) between a transmitter and each antenna. The transmitter is then coupled to an antenna through the frequency responsive device (7) that has a resonant frequency equal to the transmitter's frequency. If the transmitter changes frequency, it will be switched to the appropriate antenna through the corresponding frequency responsive device (7). This system permits a sector of a cell to increase the number of frequencies in that sector to handle increased mobile traffic loads.
