Right, one of the 12.5 kc. in-between channels would be less likely to have something on them. > > Another question, who makes a good splitter, and how can I know I am > getting a good splitter? Well, I've seen 50 ohm splitters quite often at hamfests. I don't have a good brand name to point you to. I am, however, using a 75 ohm TV splitter. Purists will hate this, but especially, if you are after a preamp, I don't see this as a big deal. It works just fine here with no measured loss in repeater receiver sensitivity through the system. Use quality coax and fittings. I've found that RG142 works reasonably well with the TV splitters since it has a solid center conductor. If you are not using a preamp, then you really need to do things right, using a proper splitter, and still you may lose some sensitivity. Some of you are saying, where's the quality in that splitter scheme? Well, experimentally I've found it works well here, so after initial measurements showed me that things were still the same, I'll tend to stay with what works, but ready to ditch the whole thing if needed and go another route. Sometimes <quality> takes the form of performance, not looks or perfection. If system sensitivity had suffered it wouldn't be there for more than 15 minutes. Laryn K8TVZ
