I've got a 902-928MHz phone system with a roof-mount 50 Ohm ground plane antenna. However, the feedlines that come down to the basement are all 75Ohm, RG-6 Coax. I really don't want to snake a new 50Ohm cable, so I'm wondering if there is a way to use the 75Ohm cable and insert an impedance matching network so the transceiver "sees" 50Ohms. Or will I still lose power between the inserted network and the antenna due to the impedance mismatch?
Any thoughts on calculating/designing/procuring such a network?
