I've done some work this afternoon. A long story short, I tested transmit locations inside and outside my home. The best I got was "weak but intelligible" radio check on a repeater that is 6.5 miles from my house while I was outside. I even crawled into my attic and didn't get great results. The second floor of my home is 290 ft up and my attic is around 300 ft. There a few trees that are higher than my roof, but not many.
I used my Baofeng 9G and the Nagoya mag mount 72G. I even carried the antenna on a 18" metal tray. I must have looked like a goofball. It's frustrating because I read that people say they get great results with this set up and I'm not getting much. I can receive well enough, it's having the power to transmit that still alludes me.
I did receive the advice to put a J Pole in my attic. I've also looked into a Ed Fong antenna as well. Does anyone have any experience with these antenna types?
I like GMRS and if I need to invest in a 20w - 30w base station radio I may be willing to do it. I'd just like to make the 9G / 72G work first. Thanks again!
