By the way, UVSJ combiners are getting a bit hard to find these days. Tower Guy posted a link a couple of weeks ago for a source:

I ordered a couple just to have on hand.
After rereading this thread from start to finish, this is what I gather about Blackstone's situation:
He has a DB8E pointed 210 degrees to receive UHF stations only. It has a preamp.
He has a CM5020 pointed 220 degrees to receive VHF stations only. It has a preamp.
He has a separate feed from each antenna going to a Channelplus combiner/splitter.
The output of the combiner/splitter goes to a Channelmaster amp and out to the TV sets.
Blackstone, can you confirm that is how you have your system set up? If not, can you describe further?
