Okay, the weather Gods have smiled on me and I have the XG91 up and mounted and peaked on channel 57.1 and it is SOLID.

Overall, I have to admit that the long yagi Digiwave 7285 is pretty close!

I know this is subjective but my channel 57.1 came up 10% when compared against the XG91.

Just to let you all know, I managed to swap the antenna out in about 15 minutes.
I doubt conditions would have changed that much in that time frame to cause a 10% difference in signal strength.

I'll be mounting up the second XG91 for my channels 2.1/4.1/7.1 with a separate preamp and coax. ANd will feed it to my ATSC tuner in my satellite/PVR receiver. The ATSC tuner in the satellite receiver is more sensitive then my Panasonic Viera.

Will keep all advised
cheers
