Title: Antenna Calibration Beacon at 2.45GHz Post by loose-electron on Oct 27th, 2009, 10:13am Hey all - When doing antenna characterization, in order to get absolute measurements, you need to do an antenna range calibration procedure. One of the things needed to do that is a reference source at the center of your antenna range with a calibrated output power. You can build it yourself or buy the thing. There is a device out there for this, I have seen it, and I am looking for the manufacturer/source of it. It consists of a standing 1/4 wave antenna, over a metal ground plane (about the size of a pie plate) and is a calibration beacon for putting out a defined amplitude signal. If I recall, it's battery powered. Anyone know the name or source on this? I am sure its buried on the internet someplace, but I can't find it yet. thanks, jerry |
