If you’re in an older home, you’ve probably seen flat cable like this coming from your antenna. It was the standard for antenna cables until the mid-1970s when the familiar coaxial cable took over. Coaxial cables have better shielding but they’re more expensive to make and until cable TV came in, the demand for them in homes was fairly low.
If you have this kind of cable in your attic or connected to an older antenna, it’s got to be fairly old. If it works for you, if you’re getting the TV reception you want, then it’s probably not worth replacing. However, the odds are that any cable that’s been exposed to sun is getting pretty corroded and if the bare copper is visible anywhere it’s probably turned very green by now and isn’t much good.
Rewiring should be a breeze with any RG-59 or RG-6 cable available at Solid Signal. At the antenna site, you’ll need a matching transformer that’s outdoor rated at the point where the 300 ohm cable formerly connected to the cable, and after that you can run that coaxial cable as far as you need. If you exceed 300 feet with an antenna or if you are using splitters, you may want to use an amplifier.
Chances are, you’re using a transformer somewhere down the line to convert that signal to 75 Ohm coax since it’s pretty rare to find a TV with 300 Ohm inputs anymore. You might remember that TVs used to have a pair of flathead screw terminals for antenna inputs, but it’s been about 30 years since you’ve seen that commonly used.
If you’re not having trouble right now, you might ask yourself if it’s really worth it to rewire everything. It’s possible it isn’t, but that really depends on how important that antenna signal is to you. If you really depend on it, then it’s worth taking care of. Trust me, the one thing that is for certain is that cable isn’t going to get any better. It’s only going to keep corroding and keep making your reception worse.
