Providing Power Over Ethernet to Silicon Dust HDHomeRun EXTEND

I installed a HDHomeRun EXTEND (HDTC-2US-M) with an Antennas Direct DB4e and a VHF Antenna Retrofit Kit.

Since the EXTEND ships with a 12V 1.5A power supply with a 3.5mm x 1.35mm tip, I used an 802.3at 12V/2A PoE splitter with a 5.5mm x 2.1mm to 3.5mm x 1.35mm tip adapter.

Power Usage

The 802.3at PoE splitter was attached to a PowerDSine PD-9012G PoE midspan. I (unscientifically) measured this power consumption of the EXTEND from the midspan:

• 5.4w - idle
• 8.2w - watch 1 channel in HDHomeRun tuner app
• 7.2w - 1 tuner active, not streaming
• 8.5w - 1 tuner, original format (Plex) recording
• 9.5w - 2 tuners, original format (Plex) recording
• 8.5w - 10.1w - 1 tuner, highest quality (Plex) recording
• 12w - 2 tuners, highest quality (Plex) recording
