Advertisements This may be an odd question but here goes. When I received my tuning adapter from Spectrum the ends of the coaxial cable included had a large plastic knob which made it much easier to screw on to the TiVo and the TA. I make most of my own cables and would love to find these as I have arthritis and this makes it so much easier to screw on. I have looked everywhere on line with no luck. Does anyone know if they have a specific name or where to buy them?? Any help would be appreciated. Thanks.
