These are the slides for my tongue-in-cheek talk to the club in April 2011.
I designed the antenna parts using Protel and got them cut out using the LPKF M60 rapid prototyping machine.
Since the 2m frequency was within the range of my AIM 4170C antenna analyzer (max 180 MHz), I used it extensively for designing and verification of the matching network.
Hope you enjoyed this presentation!
The antenna has survived the elements since Apr 2011 and is operational to this day. 4 Aug 2013
