Description The StarTech HDMI over Cat5e HDBaseT Extender (ST121HDBTE) is designed for robust, long-distance video distribution. It supports Ultra HD 4K (4096 × 2160) at up to 30 Hz, delivering sharp, clear images even when the source is far from the display. Using standard Cat5e or Cat6 cable, the extender transmits HDMI signal and digital audio (up to 7.1 channels), making it a smart choice for high-fidelity setups. Thanks to Power-over-Cable (PoC), you can power both the transmitter and receiver from a single adapter — greatly reducing installation complexity. The included mounting brackets and compact aluminium housing make the units easy to mount in racks, under tables, or behind displays.
