For TV wiring, it converts old 300-ohm twin-lead wire to new 75-ohm coaxial wire. A length of RG6 coaxial cable (I went with quad-shielded)Ī balun is a device that converts between an unbalanced signal and a balanced one.A balun (or “impedance matching transformer” as Radio Shack calls it).But for the antenna wiring itself, you’ll only need two things: What You’ll Needĭepending on your house’s structure and other factors, you may need some hand tools. However, my dad remembered it working quite well for analog TV, before cable was available in our area, so we decided it was worth the risk to try wiring it back up. In our case, the antenna was a large, 1970s multi-directional behemoth that was hanging in our attic, unused for decades. While newer antennas might be better-designed, older antennas may work just as well, provided they’re large enough and (if they’re directional) positioned correctly. The antenna doesn’t care what it’s picking up it just passes signals along to the tuner (be it a tuner box or an integrated tuner inside your TV), which decodes them into a format that can be displayed on your TV. TV antennas don’t differentiate between analog and digital signals – they’re just collections of metal rods that pick up UHF and VHF transmissions at certain frequencies. In reality, though antennas can be designed for better reception (producing few or no digital artifacts), there’s really no such thing as a digital TV antenna. You might’ve heard of “HDTV” or “digital” TV antennas. But will your old antenna work with modern, digital TV? If you live in a rural area (or a crowded urban area) where rabbit-ears just don’t cut it, your house might already have a medium or large TV antenna installed in the attic or on the roof. But there may be times when you’ll miss your local channels, whether for emergency news and notifications or just local programming. A lot of great content is accessible via the Internet, from sources like YouTube, Netflix, iTunes, and others. Cutting the cable (or ditching the dish) can be a great way to save money.
