July General Meeting: Introduction to Antenna Modelling

The next AREG meeting will be held on Friday 21st July, starting at 7.45pm at the Reedbeds Community Centre, Fulham.

We are pleased to announce that the speaker for the July meeting will be Paul Lawson VK5SL. Paul will be introducing you to the basics of Antenna Modelling, and will demonstrate how to get started using the 4NEC2 program to examine antenna performance (4NEC2 is freely available on the Internet). He will take 3 of the antennas that Chris VK5SA described in his wire antennas for beginners talk a few months ago and show how you can visualize their radiation patterns and what their characteristics are on various frequencies.

In particular, Paul will show you how to model a basic dipole, a Windom (OCF Dipole) and an inverted V antenna, explaining how to define these in the software, what the components in the software do and how to set them to produce useful models of how the antenna is performing. This will be a great simple introduction to the topic of antenna modelling.

For those who then want to delve deeper, Paul has agreed later in the year to run a tech night where more complex antenna modelling will be examined for those who want to take it further.

We hope to see you at the club on Friday July 21st. Doors open at 7.45pm with the presentation getting underway at 8.00pm sharp.
