Making additional antenna is quite simple, the materials you need to do is solder and tin, and the materials you need to have a male jack to your television antenna, and cable television antenna with a diameter 1cm. Manufacture is also very easy, first peel the skin from the cable antenna, there are two cables inside, fiber cables are used for grounding, and a single cable is used to radiate. The second stage, after the cable peeled, soldered fiber cable or grounding to the body of a male coaxial TV antenna. Glue with a strong lead, and then input the single cable and attach to the modem.
