We had 300 ohm ribbon back when we had VHF TV. When we went to UHF in the '90s we also changed to coaxial cable

Coaxial cable works better at higher frequencies than 300 ohm, but needs shielding. 300 ohm doesn't need shielding as any wave that hits it hits phase and anti-phase at the same time and has no effect
