Thanks for the help guys. I got the AntennaCraft C290 and I'm getting all my channels. I had to point it at 261° to get 27. Luckily I still got all the other channels too.
I looked at the manual for my old antenna. It does say to use additional power injectors as required. When everything was working I may have been able to make it work with one injector before the split but it would have been difficult to get power to where the split is. Anyway, I'm power free now and happy.
