What is the difference between an SDM38VHIR and SDM38VBIR?

The SDM38VHIR incorporates a high headroom amplifier. It should be used only for off-air antenna signals and CATV services that DO NOT require a return path for interactive applications. The SDM38VBIR is a bi-directional device, with a 5-42 MHz return path for use with CATV systems that provide interactive services such as Cable Modems and Pay-Per-VIew. It should not be used for off-air antenna signals.
