For an old style TV box, the has modulated output on Chan 3? Or is the tuner DTV ATSC only?
You don’t specifically ask anything…
That’s because Roku offers no way to connect an antenna directly to its players.
Roku has no* input or tuner for television channels 3 - 49 or 68.
Sorry, I meant from the RF antenna side. If a band pass filter introduces an analog signal on VHF 3/4 from an old cable box.
The Tablo’s tuner is ATSC only. You can’t record an old analog NTSC signal with it.

Near the bottom of each page… not exactly what you asked, but similar:
No. Tablo is designed to record and stream Over-The-Air (OTA) broadcast signals from ATSC TV antennas. We do not support recording from cable or satellite signals, cableCARDs, or clear/unencrypted cable (QAM).
No, that was easy.
