OK, I have the HR10-250 w/ a 3LNB dish. I bought an OTA antenna and have it set up correctly when it is connected directly to the HR10-250, but I was told when purchasing the antenna, that I could connect it directly to the multi switch and then use a diplexer at the box. Two problems, one is when I connect it the way I was told, the box did not pick up the signal and two, I have a four input multi switch and they are all being used up by the directv/tivo lines from the dish. I would hate to buy a new multi switch if connecting the OTA antenna through it doesn't work anyway. Any ideas, suggestions or places I can go to get more info? Thanks.
