I no longer recommend them, though I still have one in very active use here.

The tuners inside the HDHomeRun units are simply antiquated by current standards. Adequate for strong local signals, but unable to even get a sniff of weaker, more distant stations.

Nowadays, my alternative recommendation is a pair of HVR-950Q USB sticks, when external tuners are required (eg. due to a shortage of internal PCI/PCIe slots).

Cheers
