Hi All I have a roll of government surplus coax that looks to be good for duplexer jumpers.
It looks like RG-214 or RG-217 without the outer jacket. It is double shielded silver plated shields with black jacket between the shields. It has no outer jacket, so the outer shield is visible. The inner conductor is solid copper that looks to be about 10 gauge. The insulator looks like PVC. The roll tag indicates that is was made by Plastoid. It fits into a UHF connector if the inner conductor is sanded down slightly and the outer shield is clamped to the outside of the UHF barrel. I used screw clamps. I have about 60 feet I would like to sell for a $1 a foot plus shipping. Email direct at NJ7J @ arrl. net. Byron NJ7J
