An elderly relative has an antenna like that. It's never failed, it's the only antenna ever installed on their house. Literal LOS and within 15 miles of Mt Mansfield means that it works since the transition as if nothing happened. The VHF Montréal channels are flawless, too. Before the transition, UHF was weird looking, snowy, no Montréal, and missing the lower power channels, but ABC and PBS were watchable.
The TV it's attached to is ancient and stops at Ch 36 (I think) so the digital transition gave them Fox 44 and WCFE since the analog tuner didn't get them, but the converter box did.
