Model B-300
The B-300 Balun for Video Audio and Power provides the
necessary impedance transformation to transition from 75
ohm coax to twisted pair cabling. It is a great way to deliver
video, audio, and power from a security camera when you
only have a CAT5 cable running to the camera location and
no coax. The low cost, simplicity, and availability of twisted
pair cable, makes the B-300 a convenient choice for both
new construction and retro-fit applications.
