Yeah, I was expecting that the whip would give me a significantly reduced range.
I'm going to order some and experiment. It'd be really neat to hack a system like this together. 5 miles is my target (which would be 1/8 of the max point-to-point range. My concern is that I might be able to get 5 miles omni-LOS, but that without a clear line of sight I'd be down to half a mile or so.
