Does anyone have a good idea of minimum bending radius for the 1/2 inch cable TV hardline? I have been

Like Andrew LDF Heliax?  5" is the min bending radius..

The thing to remember is not so much the bend radius, but, rather, you only get to bend it once. Each time you bend it, it work hardens the copper a bit, leading to cracks, etc.

Also, if you're going to bend it that tight, you need some sort of mandrel or bending jig to support it. Think of bending copper tubing or electrical conduit. (in fact, a conduit bender might work real well for this application)
