Sorry for all the questions...
on my 100.4 I have I believe 4 lines running through the tube of the antenna and into the LNB jobby....
There are no diplexors by the satellite Antenna. I do however have 2 sets of Diplexors by my 722. A single line comes out of the wall... goes in to a diplexor, one wire I think goes into TV 2, then the other line hits another diplexxor and is broken into the 2 satellite ins on the receiver for a total of 3 lines into the box off of 1 feed.
Do I splice the OTA antenna into the main line coming out of the Satellite Antenna and add another diplexxor to my receiver so I have 4 lines running in? (kinda sounds like an awful lot of splitting of signals to me) but then again, if the picture gets any better I'll be able to see inside people's nose pores.
