Yeah, I read through that some time back. For the life of me, I can't remember if the system I bought is GP or NGP. Quite frankly, I think I must have gotten the NGP because things seem to be working quite nicely. I'm sure it'll be even better after the antenna gets a tune. I need to find an excuse to come over again, Matt!

I did have to do one little mod for my setup. The hole on the new mount is larger than the standard 3/8" size. I bought a couple of 3/8" stainless steel washers to sandwich on the stud for good measure.
