For $99 I would take the risk to damage it... Or find someone with x-ray gear and have a peak inside. Or take it with you on your next plane flight and grab a photo of the TSA monitor as you pass through. > My antenna testing abilities are pretty feeble. > Mostly, I will just compare it to the Leica and Trimble to see how many > satellites it sees and look at position wander of the uBlox.

If you're a mm survey kind of guy then mix that antenna with half a dozen name-brand antennae that you already own and trust. See how it stacks up in real-time or post-processing benchmarks. I'm a fan of measurement more than specs, so collect as much data as you can and share with us. If you're a time-nut it's more complicated. It's possible you don't have anywhere near the kind of equipment that can detect sub-10 ns sort of bias or wander or noise. And then there are issues of orientation, elevation, linearity, thermal stability, etc. If it's not in the NGS database be suspicious.
