Brian Howie GM4DIJ talked about and demonstrated Antenna Modelling Software at the LRS meeting on 11th March 2015.
Brian writes: “The design and building of antennas at one time required vast testing ranges with expensive equipment. Analysing and optimising antennas once took many hours of painstaking measurements, hand calculation (if you understood the maths) and modifications with no real guarantee of success.
Modern software now allows you to determine the pattern, feed point impedance and even the SWR of your antenna system before committing to cutting metal or hoisting wires thus avoiding expensive or time consuming mistakes”. Full report.
