So I looked up the manufacturer, and found it was a company called Shenzhen Afoundry Technology Co., Ltd. In China of course. Wholesale wise, the minimum order is 1,000 units. Their website looks a little stale (2007 ?)
My question is does anyone have any experience with this companies equipment?
I did not see any statistics on the Front-to-back ratio or Azimuth and Elevation charts to back up their claims. Yes I know that 1/2 power widths can be estimated from the dBi rating, but I would prefer real data.
