The other is > Belden 8219, which has a cellular polyethylene core and a NVP of 78%. Since Belden/DEC spent considerable effort to design a GOOD thinnet cable. There are many not so obvious things that got considered that have been documented enough times already. This cable (and other similar 'LAN-grade' cables) may not fit RG58 size BNCs. This isn't really a problem. Just order the BNCs that fit. The Belden numbers are: vinyl 9907 Teflon 89907 Belden has a new air-plenum grade cable insulation that crinkles less and is less expensive than Teflon, and I assume they are also making this cable using the new insulation, but don't know the number for it. DO get Belden, not the many other brands that are qualified to DEC's spec. Little problems (like getting the foil to strip easily...) can become major pains with cheaper wire. The actual price difference is tiny, so get the good stuff. Try 1.800.BELDEN4 (NOT 1.800.4BELDEN ).
