</blockquote></div>Oops, that's not exactly correct. I mean two or more inputs are connected to an upstream exclusive access device (which means it can only be tuned to one channel or a subset of channels which is excluded from the other inputs connected to the device). I mentioned antenna because I seem to recall one user used input groups to solve the "antenna on a rotator" problem where only certain channels could be received in a particular direction.<br><br></div><div class="gmail_extra">Karl<br></div></div>
