Tim Pierce wrote I have worked with sites that used the hardware cloth (screen) over concrete in the past. When the tears would happen, they would patch that area ... Tim, If this were a reflector antenna, holes in the reflector would be kept to 0.1 wavelength at the highest frequency. This

Re: another OATS question

Hi Ken, Only the maximum reading over the scan height is used. The received signal is nominally the vector sum of the line of sight path and the reflected or image path from the ground plane. In horizontal polarization there is also 180 degree phase shift due to conservation of charge physics

RE: another OATS question

Hello Tim At one of our OATS sites we have a pit under a metal hatch in the groundplane, to the rear of the EUT turntable. To do the NSA we put the signal generator down there and connect it back to the control room via a fibre optic/GPIB link. I wrote some software which steps the sig gen
