As a follow up to this:
I went back and looked at my earlier notes from other posts and couldn't figure out where I was getting the "Not allowed to use the homes electrical ground" until I did a search online and came across the original post (From here coincidently) from 2013 which does say it's a not legal to tie into the ground for the electric service. After reading it again (This time with a full measure of coffee in me) I realized the reference ("power company grounding system") was to the Utility company's electric service. IE: the pedestals they maintain on the property and not the electric service for the house.
As freaking foolish as I feel right now, I am also REALLY grateful for getting the correct information from tweiss3 and having Jones warn me off using the lightning rod grounds at my home.
Finally, thank you berkinet for asking the question about whether there are any stations I can't reach with my existing setup. The way I was setup in the attic was having a 6db omni antenna for hitting the local repeaters and a yagi that was aimed directly at my brothers house 15 miles away since the onmi directional didn't have enough "oomf" to have clear communications and the repeaters were pretty scratchy and noisy when I used the Yagi since it was not aimed in their direction. I had 2 separate runs of LMR400 that went into a coax switch that allowed me to flip between the 2 antennas. This worked as long as I had the switch in the correct position depending on who I was trying to reach. After pondering all the stuff I was going to go through getting an outdoor setup to allow using just one antenna I played around with the Yagi in the attic (And man was it hot up there this weekend!!!) and after several trips up and down the ladder I found a compass position that was between what the heading would be for the repeater I frequently use and my brothers house. The end result is having useable communications with the repeater and my brother!!!
Granted I do a have slightly higher background noise. But is is REALLY slight and from everyone I talked to they can tell a difference but it's nothing objectionable.
Maybe I can sell off the extra LMR400 cable and the omni directional antenna and put the proceeds towards a rotator for the Yagi.
For now I will enjoy not having to check which antenna the switch is on to make contact with whoever.
And I will wait for the temps to cool down a little.
Thanks again to everybody who responded to this post!!!
