Unless your tv has an internal ATSC decoder, you won't get HD by running the antenna directly to the tv.
The splitter suggestion would allow you to record SD OTA (standard definition over-the-air) content to an analog vcr, while watching HD OTA via the E86. For example, with a splitter you could set a standalone VCR off to the side to record the OTA SD feed of xxx on channel 2 while watching yyy in HD via your E86. Take note, however, that you cannot watch high def and SD on your tv at the same time via the Picture-In-Picture feature.
Make sense?
