Coaxial cable is frequently used to install cable and satellite television service where an inexpensive and reliable medium is needed for transmitting video and audio signals. When running cable inside a building, it may not be possible to install cable in a straight line. Instead, the cable may need to snake around corners and walls to reach its destination. Coaxial cables can be bent within the limits typically printed at regular intervals along the insulation over the cable. Exceeding these limits can damage the cable, causing signal loss and reduced performance.

Hold the coaxial cable in both hands.
Bend the cable gently to the required angle, but no more than 90 degrees. Bending the cable more than 90 degrees may damage the wire conductors inside.
Measure the distance from the coupler on the end of the cable to the straight section of cable on the other side of the bend.
Take a measurement from the middle point of the measurement in Step 3 to the inside centre of the bend in the cable. This measurement is the bend radius -- for example, 3/4 inch. Compare this measurement to the bend radius rating printed on the cable. If the rating is less than the measurement, the bend is too sharp and may damage the cable.
Straighten the cable and relax the bend until it is within the rating printed on the cable.
Tips and warnings
- Electronics and hardware stores have 90-degree couplers. These connect two separate coaxial cables at the point where a right-angled is necessary for installation but would damage a single cable if it was bent that far.
