Abstract
This paper describes the continued characterization of a printed-circuit-board log periodic dipole-array (PCB-LPDA) antenna used for radio frequency interference (RFI) measurements for the South African Square Kilometer Array (SA SKA) project. Earlier measurements in an anechoic chamber showed levels of uncertainty in the VHF and C bands. Measurements on an open area test site (OATS) show lower uncertainty results for these frequency ranges. Simulations using the computational electromagnetic code FEKO give more insight into the differences between measurement results below 150 MHz.
