Compared side by side
The AV Access 4KEX70-H2 HDBaseT HDMI Extender Kit (transmitter + receiver) appears in this table next to models from other brands:
Who it's for
Cable routes from the booth to the projector longer than 49 ft and up to 197 ft on Cat5e/6 or 230 ft on Cat6a.
Caveats
- AV Access says it works only over a direct cable from transmitter to receiver, not through an Ethernet switch.
- One transmitter works with only one receiver. Plug the receiver into the projector's HDMI input. AV Access doesn't say the transmitter works with a projector's built-in HDBaseT port.
- At 4K the reach drops to 115 ft on Cat5e/6.
- The Cat cable isn't included. Use T568B straight-through cable, as AV Access recommends.
