Good wisdom Joe. One of my favorite cables for interconnecting is 1/4" Superflex. If using UHF connectors (not necessarily my favorite, but I use them and rarely change them to N), it fits perfectly into the larger adapter (for RG59). Solder the solid shield to the adapter, then solder thtough the holes to the adapter. Use all silver plated pieces. Makes a decent cable with low loss and low noise for duplex work.

RG-400 and RG-142 will give about 75 dB isolation from leakage. Foil & braid shielded coax will give about 90dB.

I would use the N connectors that you have and then use a GOOD quality adapter to take it from N to UHF (not radio shack). Better yet would be changing the connector on the radio to an N. > > RG-400 or RG-142 would be the easiest. You could probably fit a UHF connector easily to this cable for the equipment end, and an N connector on the other for the duplexer. > > I would stay away from foil & braid shielded coax. I have never been happy with either the crimp or the compression connectors for this style cable. It can be used, but extreme care is needed to get a good quality connection. Then there is always the argument of noise.......... > > Remember, some repeaters work perfectly well with RG-8 jumpers on the duplexers. Commercial duplexers sometimes come with RG-8 interconnecting cables. If you are trying to solve a desense problem, it may not be the jumpers that are causing the problem. It never hurts to use the best, but it may not be the fix for the problem at hand. > > 73, Joe, K1ike > Yahoo!
