I've had excellent cables from these guys on eBay and I've bought some in RG-316 Teflon and also RG-58. I would recommend jumpers made from RG-58 with stranded center conductor like RG-58/AU or /CU. American Coaxial Industries | eBay Stores
The few Chinese made cables I bought all came apart at the connector like the crimp ferrule didn't fit the outside of the coax properly.
