BackgroundThe“$50 HF Antenna Analyser” started off life as a presentation forPacificon 2013.Theinspiration was what someone could do with a $5DDSmodule found on eBay and a $35Arduino micro-controller.D uringearly development it was discovered that using a PIC instead of theArduino brought the price down to under $25. ThePIC is used to sweep an AD9850 DDS and measure the forward andreverse detector voltages from an SWR bridge at each frequency andreturn the values to a PC for plotting on the screen.The following picture shows a comparison of the Antenna Analyser shown at the top of the page with the hand-held VNA.
