Tape, rope or wire - what do you choose? The primary concern is visibility. For many animals an electric fence acts as a psychological barrier and they must be able to see it to avoid it. Products which offer a higher contrast with the surrounding environment are more likely to be effective. Tapes and ropes are more common in equine applications. Poly-tapes, ropes and wires conduct power through thin metal conductors running through the length. The more metal in a fence line the more efficient it will be. Products with a combination of both steel and copper material conduct the most effectively. A lower Ohm value indicates the product offers less resistance to the energy flowing through it and thus will take the power further.
