Co-Phase Coax

Use a co-phase harness for dual antenna installations. A single coax is 50 ohms. A co-phase harness is 72 ohms before it splits into 50 ohms for each antenna. This is important for a good SWR. If you try to connect two single coax lengths to a T connector for dual antennas, you may run into high SWR issues.
