Home made cable lifters.

Use plastic rebar chairs! All colors and sizes available. These are the devices that hold up the steel reinforcement "rebar" on concrete slabs. Go to any development in progress and ask a foreman for a few. Tell him you are pouring a small slab to avoid any funny looks. You might also find them in hardware stores, but in large quantities. Do a search for "concrete chairs". Here is one manufacturer.

I can understand lifting a cable from a concrete slab (which is what I have). After all, there is steel reinforcement underneath. A solid chunk of steel has exponentially more effect on the impedance properties of a cable that "artificial fibers". I'm not even going to comment about the artificial fibers vs natural fibers debate. Good grief. I made this recommendation because these lifters look a lot more "professional" with expensive cables than wooden teepes or styro cups. Just a suggestion, nothing more.
