Hello I need some advice - I've searched the group and can't find an answer, so I call on the collected wisdom here, but apologise in advance for taking your time.
I have a repeater site that has a single antenna, VHF and UHF. Now, combining the VHF and UHF is fine, although lossy. But, we want to add D-Star at 70cm, which means that I will have two UHF repeaters, two sets of cavities. How do I combine the output of the two cavities prior to feeding to the VHF/UHF combiner ? My frequencies are close: D-Star TX 439.6125 FM RX 434.650 FM TX 433.050 D-Star RX 430.6125 Do I just couple to another T-piece ? Are the cable lengths critical ? Has anyone got experience of doing this ? Thanks in advance for your assistance. David - G4ULF
