Ask Slashdot: What Can You Do With Old Coaxial Cable?

Posted by EditorDavid on Sunday July 30, 2017 @12:02AM from the home-improvement dept.

Long-time Slashdot reader Theaetetus writes: I recently bought a house and the previous owner left some coax (mostly RG59) running between rooms for cable distribution. I'm a cord cutter and don't need cable, and I've already run CAT6e everywhere. But before I pull the RG59 out and try to seal the various holes he left, I figured I'd pick Slashdot's brain: can anyone think of a good non-cable use for spare coax lines?

+1 - I used the existing coax cable in a home I had as a WiFi repeater (really more of a waveguide). Reception was weak in a back bedroom, but there were cable drops in there as well as beside the router (hot spot), so I stripped little stub antennas and attached them to the in-wall cable, boosted reception in the back room from flaky/marginal to pretty stable - cost: near zero, installation time about 10 minutes, ongoing expenses: none.
