BZBGear BG-EXHOC HDMI Extender over Coax

Existing coax is often the only cable already in the wall, and the EXHOC uses it: one RG6 run carries 4K60 4:4:4 8-bit HDMI up to 110 m. In a retrofit - a hotel, a bar, a house with cable TV wiring - that avoids pulling new category cable through finished walls.

The transmitter takes HDMI and puts BNC out; the receiver does the reverse. IR passes in both directions on 3.5 mm jacks so the source can be driven from the display end. Both units are 90 mm metal boxes on a locking 5 V supply.
