I used this device to extend HDMI signal via Cat5e (1 pair), tested on Astro Beyond, picture & sound quality totally the same no degradation at all !!
Only concern is required to lay 1 pair of Cat5e
2 model design, 1 for distance up to 30m (no need power adapter), another type for distance up to 60m (require power adapter to boost signal).
This model for distance up to 30m, no power adapter required.
This device for distance up to 60m, require power adapter to boost signal.
