Claim 9:
10. A system for measuring gain for an antenna under test comprising:
a lossy half-space boundary;
a first mount for mounting a phase center of the antenna under test a first distance directly above said lossy half-space boundary;
a second mount positioned a test distance horizontally from said first mount;
a probe antenna positioned on said second mount with the probe antenna phase center a second distance directly above said lossy half-space boundary; and
a controller joined to said probe antenna to receive a signal from said probe antenna and joinable to the antenna under test to provide a known signal to the antenna under test, said controller calculating electromagnetic signal parameters from the signal received from said probe antenna.
