All of this really doesn't matter because I can't change it.
It is from one corner of the house, single story, to the opposite diagonal corner, so maybe 70 feet. It goes through several layers of drywall and given the structure it's probably 8 walls. Also the kitchen is between the points so I have the metal in the microwave to deal with, it's not an issue of running the microwave since I wouldn't do both at the same time, just the metal.
The arrangement is pretty well set which is why I am trying to throw more power into the direction I need.
