you can get pack of balloons $1..2, fill them with air partially using hand held pump and knot them around cable in several spots so you can place them on top of balloons. if you're creative enough with balloons, you can make 4 legs out of one balloon instead of 2.
it's going to make you an AIR BEARING SUSPENSION of wires for $2 not for $200.
not sure if it will make difference, but cables definitely will be elevated. while paying $200 is definite snake oil call, paying $2 washes the snake oil off and gives you room for cheap experiment. if you find this interesting and entertaining you can make money on your own snake oil selling same mentioned above CABLE AIR BEARING SUSPENTION or CABS tm.
