For a 2 foot cable, I don't think the loss will be significant whatever cable is used. Cable loss for RG8 is about 1.6 dB / 100 ft at 50 MHz. Cable loss for RG8x is about 2.5 dB / 100 ft at 50 MHz. Cable loss for RG58 is about 3.3 dB / 100 ft at 50 MHz. So 2 ft of each would be 0.03 dB or 0.05 dB or 0.06 dB, all insignificant. Connector loss is on the order of .1 dB per connector. So, more important will be the quality of the connectors and the quality of the cable shielding. I use way better cables than required, so I would not be a good reference point, but I use a lab quality RG58C/U cable containing a stranded center conductor (for flexibility) with two BNC connectors and an adapter between my KX3 and amp. Don't buy cheap no name cables from Amazon or eBay.
