EMAX Pagoda-2

This is the version of my own Pagoda antenna which is sold by EMAX. These units were sent to me by EMAX.

The heat shrink shifts the frequency down a bit, but not by much. I had the impression that the PCBs were not always 100% parallel on all units, which may degrade the axial ratio a bit, but nevertheless the matching and consistency of the measurements is pretty good. I measured a total of 8 units.

I have no anechoic chamber measurements for these units, but I do have them for my own Pagoda-2 antenna, which should have a similar radiation pattern.
