Thank you majortom and Jase88. I replied in the TVFool forum this morning and nearly forgot to check this thread. As far as the Vhf-Hi antenna is concerned, I don't really know the make and model of it. I salvaged it and repaired it. If I remember correctly, it's a 9 or 10 element yagi. Ion on real channel 12 is coming in, as well as WHTM on real channel 10. I really do think that TVFool may be off on real channel 8 because a single antenna will pick it up (either 8-bay or yagi) by itself no matter which way it's aimed. If it wasn't for WGCB on real channel 30 (49.1,49.2,49.3,49.4) coming in at an odd angle (almost 90 degrees to the left of of the Harrisburg stations), I'd probably just not use the 8-bay at all. I'm thinking that both antennas are grabbing real channel 8 and the signals are interfering with each other. So, my first plan is to use only the Uhf side of a UVSJ (and terminating the Vhf side) on the 8-bay before the preamp to try and further filter out any Vhf-hi signals. Also, to test my theory, I'm going to try unplugging one of the antennas to see if they actually are interfering with each other. I won't be able to try anything until Sunday as it's a 2-hour drive from my house to her's. Rabbit73 ran a FMFool report for me and didn't see any strong FM stations that would interfere. It's been a bit of a puzzle, but I think that's why I enjoy this. Again, thank you for all the help. You guys are awesome.
