Reading this I'm assume that you are talking about a repeater installation and not an installation for working the repeater. I'm basing that on the remark that the area is fairly flat over a 60 mile

I think some worry far too much about what others do. I have a number of pursuits that others would consider unsafe, one of which is aerobatics. Even my insurance company won't insure me while doing
