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.

Steve (and everyone else) please re-read slipknot1's 11-16 post above. He says plastic is a no-no and I agree with him on this point.

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.

If you have a gas high temperature kiln, shape or mold the shape you need and apply a salt glaze and fire. If not forget about anything other than high fire ceramics.

Wood, glass, plastic, and even paper in my experience do not do the job. Even unglazed ceramics like bricks are no good.

I have found that discarded ceramic electrical insulators such as you might find outside your utility company can be very good, although they might not have WAF.

We do agree that lifting cables off the floor(especially carpets) make a(good) difference. I can't lift my cables the 8-inch recommendation of Mapleshade(I'de also note that Mapleshade recommends power cable lifting, also.) I also appreciate the two manufacturers responses here. Tgb, can you purchase what you suggest, without doing anything to it(for us nimrods).
